According to Fox News, Fox blames her recent dramatic weight loss on a role in Jennifer's Body, a comedic horror film penned by bloggy-inclined Oscar winner Diablo Cody in which Fox plays a "possessed cheerleader." But master fauxter Bay, demanding as ever, has forced Fox to stuff herself silly with late night binges in order to bulk up for Transformers 2: More Shit Blows Up! And as for poor Anne Hathaway? Not only has she allegedly dropped almost 30 pounds in the few weeks since thieving ex-boyfriend Rafaello Follieri finally got nailed, but she's also said to be "throwing herself" into work on Bride Wars, that glee-filled set where disguising her hatred for co-star Kate Hudson has become close to impossible. But hey, at least now Anne can come out the winner in those infamous skirt size comparisons she and Hudson indulge in every time the cameras stop rolling!

Nicole Richie was back to her old uber-thin self just two weeks after Harlow graced us with her presence earlier this year, and Jamie Pressly openly admitted to losing 42 pounds in 12 weeks by "only eating cabbage soup." The rest?

After having Moses, the current nudie pic exhibitionist says she makes sure all those pounds which initially "horrified" her remain at bay due to her after-hours habit of downing red wine and passing out in the garden. Who has time to eat when you're unconscious? Hubbard Formula aficionado Leah Remini claims to have lost a whopping 80 pounds in only six weeks after ordering something eerily called the 1st Personal Diet. Remini told TV Guide, "It's determined by the metabolic rate of your blood, and then they send you a diet on your e-mail." Why hasn't anyone informed Oprah of her computer's flesh-zapping knowledge?

Jennifer Lopez made a public appearance looking just like J. Lo circa Diddy only a month after popping those expensive twins out, and reportedly managed the vanishing act by shelling out $50k on a home gym, not to mention hiring a team of trainers, nutritionists and Baby Weight Loss experts to presumably make sure she never once stopped exercising. Finally, Gwen Stefani candidly told Elle that she was utterly obsessed with getting her figure back after little Kingston arrived. The only celebrity to go ahead and admit that the ways stars do it is just a bit horrifying, Stefani said she was so adamant about the process that she was still exercising two weeks before giving birth. And cried about it. Live and learn.

• OH BABY! JESSICA ALBA SHOWS OFF HER FABULOUS POST-PREGNANCY FIGURE [Daily Mail]

According to the not-yet-out piece, The Hills’ Audrina Patridge, nude photo aficionado and recent recipient of a brand new pair of boobs, is so focused on maintaining her widely-seen curves that she sports those 4-inch health-impairing stilettos every Sex And The City fan thinks will turn them into Carrie Bradshaw while cleaning house. And thin-as-a-rail Friday Night Lights star Minka Kelly uncomfortably yammers on about how she once weighed in at an apparently unacceptable 135 pounds and “literally stopped eating...I’d do Bikram yoga and go to bed. I lost 15 pounds in one month.” We hope the John Mayer tossaway can forgive us for not immediately rising to our feet and giving Minka a standing ovation.

Even picky sperm selector Denise Richards goes overboard in her interview, treating the TVG reporter like a shrink and leaning on her oft-used plea for pity by referencing her recently passed mother: “After my mom died last year, I gained at least 10 pounds. I know because TMZ was kind enough to publish pictures of me looking very, very soft in the stomach.” How refreshing to discover the secret to overcoming grief caused by the death of a family member: just obsessively google images of yourself in a bikini and concentrating on going down a jean size or two! As for the self-professed chunky toddler, A.C. Slater-turned-reality-trash-host Mario Lopez says he “never feels awake unless I’m sweating,” and tells the mag he exercises “for a minimum of one hour a day.” Which sounds about right, considering his current career responsibilities are limited to applying hair gel before “judging” street dance crews alongside J.C. Chasez!

Actor Colin Farrell looked slim and toned as he showed off his new ultra-thin physique on the beach in Malibu after his dramatic weight loss for a film role.

Despite his slender frame, the 32-year-old appeared tanned and healthy as he jogged along the beach yesterday.

The Irish heart-throb looked every inch the beach Adonis with his long hair, Celtic tattoos and a sand-covered six-pack.

Farrell has dramatically shed pounds for his role in the upcoming movie, Triage, in which he plays a war photographer.

While Farrell's devotion to his craft is admirable, we can't help but think his inevitable re-porking will disappoint a lot of girls and gays on the east side. To them, we offer an encouraging bit of advice: get thee to the Trader Joe's on Hyperion, where Colin clones can be had on the street for spare change and a fresh box to sleep in.

Martha's Vineyard Detox Diet: Followers include ridiculously skin-and-bones supe Gisele Bundchen, weight loss master Robin Quivers and the muscular Madonna. The 21-day detox promises devotees to shed 21 pounds in that many days "by subsisting on live juices, enzymes - and regular colonics." Fun!

The Master Cleanser: Reportedly what Beyonce used in order to nab her Dreamgirls role, Vince Vaughn allegedly follows the lemon juice liquid diet, and Jared Leto shed his Chapter 27 weight by drinking the "water mixed with lemon, maple syrup and cayenne pepper" cocktail as well. Yum!

Dr. Joshi's Holistic Detox: Fans include the clavicle-flashing Gwyneth Paltrow, original waif Kate Moss and currently slim Ralph Fiennes. The main focus is avoiding acidic and toxic foods, but the downside hardly sounds worth it, and sort of explains Kate's moody expressions in photo after photo: "Users report headaches, stomach pains, nausea and fatigue." Even more fun!

• CELEB DETOX DIETS MAY PROVE HARD TO SWALLOW [NYDN]

According to the Daily Mail, Britney has recently gone from a size 14 to a size 10 by "following a strict diet based on Victoria Beckham's eating regime." Before detailing what the tiny bobble-headed Brit's regime actually is, we'll give you some perspective. Not that anyone needs reminding, but Marilyn Monroe was the epitome of pin-up girl hot, and it's been widely reported that she wore a size 12. As for Posh? That alleged 23-inch waist of hers so often exaggerated by massive tight belts belongs to a size 00 body. Yes, those are two 0s. Whether or not Britney actually plans on downsizing to such an extreme is unknown, but we find her Monroe-esque curves of late far sexier than the toothpick look favored by Posh and her toothpick-y peers.

In any case, a source claims Spears heard how Posh "stays so thin" and has been chomping on the following oh-so-mouthwatering dishes: steamed fish and edamame beans, goji berry juice, and seaweed shakes. Well, goji berries are a favorite of ours, but seaweed shakes? Why, Britney, why? We can only hope she's at least eating the entirety of each random diet dish, as opposed to splitting each bean in half like Jacob Marley or, of course, Hubbard hostage, Katie Holmes.

• SLIMLINE BRITNEY FINDS A POSH WAY TO LOSE WEIGHT [Daily Mail]

It’s that time of the month year again! Oprah Winfrey, frequent flier on the countless and very public weight watching rollercoaster, has decided to turn her oft-used diet switch into On mode one more time. And the newest attempt at shedding pounds may be her kookiest plan yet, which Oprah says was inspired by a book called Quantum Wellness in addition to online sessions with a motivational speaker. Yes, these days those loud-mouthed mood boosters can motivate you without having to actually speak at all! So how will Winfrey rise to the get-slim-quick occasion this go-round? With tasty delights like mouth-watering tempeh and and positively sinful wheat-free crepes:

Back in 2004, Oprah credited very basic rules like "no white stuff" and the standard "drink lots of water!" approach to her admittedly trim figure as she turned 50. But apparently Oprah hasn't seen as much change as she'd like, and has chosen a far more rigorous plan this time: a 21-day detox program in which she'll not only save the animals, but give up "sugar, gluten, alcohol, meat, chicken, fish, eggs, cheese." Just like Oprah, we had to wonder, "What's left?" And the answers aren't pretty. As Winfrey blogged recently, "I can honestly say every meal was a surprise and a delight, beginning with breakfast – strawberry rhubarb wheat-free crepes." But despite her gung-ho attitude and apparent dedication, even Oprah doesn't sound so sure this fierce change in her regimen will be a guaranteed success story: "Don't know if I'm going to feel better or worse, but I'm willing to try to see if my body at least feels differently." We're not sure about her, but if we had to spend three weeks off the bottle, we'd certainly feel it — catatonic messes we may be, but "different" for sure!

As MSNBC reports, the Olsens have a friend in their bunch who we think would fit in perfectly at Posh 'n Katie's lunch table. As she says, "It’s...my worst nightmare — that and getting a huge diet fountain soda that is mistakenly regular Coke — but I can def[initely] taste the difference, so it’s their own fault." Someone's worst nightmare is accidentally drinking milk just because it's not skim? And they're friends with the Olsens? We don't think secret coffee recipes are the trick to plumping them up — it's cutting this nut case loose.

Playing a prisoner of war in last year's critically acclaimed Rescue Dawn meant Steve Zahn, until then just another token funny buddy actor, was forced to lose 40 pounds on a diet of vegetables and nuts. As he put it, "I never cheated but it was tough - I'm a meat and potatoes kind of guy." As for Renee Zellweger, earning Oscar noms for both Chicago and Cold Mountain meant losing twice that much: "I lost 80 pounds for those two roles...my tits disappeared so I had to stuff socks into my bra cup!.” And Matt Damon lost 30 to play the nerdy swindler star of 1999's bold-faced name-packed but Oscarless update of The Talented Mr. Ripley.

As a crack addict with a heart of gold in Half Nelson, Ryan Gosling went from Rachel McAdams' cute boyfriend to Oscar nominee by transforming into a gaunt tweaker. But of course, the most frightening metamorphosis of all time has got to be Christian Bale's unrecognizable appearance in The Machinist, a role which earned him just as many rave reviews as it did health problems. As Bale put it, going from 180 pounds to 120 caused "a massive shock to my body because of what I was trying to get it to do...My metabolism had to get back up to speed, because my heart had got used to a whole different way of living for some time."

• FARRELL GOES FROM TRIM TO THIN [The Sun]

As the Daily Mail reports, Britney may have giggled her way through a treadmill workout in LA last week, but "Britney's hard work may be counter-productive - she was spotted with a packet of Marlboro reds as she left the gym." Reds? Really? Not that we, ahem, smoke or anything, but our friends tell us Reds tend to wreak havoc faster than most cancer sticks. Nevertheless, a giddy cover story in Star claims Spears has shed a whopping 20 pounds since Rudolph put her on the straight and narrow. If only grumpy HIMYM star Neil Patrick Harris would quit whining about her upcoming return to the show, Britney's Comeback Tour could finally progress a bit speedier.

• BRITNEY ON THE TREADMILL: IS THE STAR SHAPING UP FOR ANOTHER COMEBACK? [Daily Mail]

"[Tom] is keen to put some distance between his actress wife and Victoria, who have morphed into each other...it concerns Tom that Katie has lost so much weight recently."

Rumors surfaced a few weeks ago that Katie and Posh are fond of splitting meals together, or ordering one tiny entree and cutting the whole thing in half (even the soda). But apparently all this dieting is turning Katie from fit to scary skinny. And Tom, in true form, isn't happy. Frankly, we wouldn't be either if our significant other was following this freaky food regiment: "She is following Victoria's strict 900-calories-a-day eating plan. She is copying Victoria's fad of eating seaweed shakes, frozen grapes and edamame beans. She is tiny." Frozen grapes and seaweed shakes? We would imagine this diet, aside from shrinking Katie's waist size, would wreak havoc on those rare once-a-month occasions when Tom insists she kiss him on the lips.

[Demi] lacked a defined waist, carried too much meat on her thighs, and was, by movie-star standards, thick overall."

Parr writes of Madonna, "When [she] and I started working together, she was very soft." Madonna, soft? Considering recent pictures of her whether she's airbrushed or not, we didn't realize putting the two in the same sentence was even legal anymore. And poor Watts, whose perfectly fit body provided the only moments of solace throughout the entirety of Funny Games gets the following distinction from Parr: "fleshy...we needed to trim and tighten so that she would fit the mold of a bikini-clad babe." Did he really just say "bikini-clad babe" in a book? Now we understand who's feeding stars impossible-to-believe bites when it comes to blabbing about how much they "chow down" to the press.

• CELEBS CLAIM TO CHOW DOWN - AND THEY'RE TRYING AWFULLY HARD TO CONVINCE US [NYDN]

"One of Hollywood's dirty little secrets is the 'IV diet', in which celebrities check themselves into hospital to get put on an IV so they can avoid eating altogether."

Lindsay Lohan's multiple "exhaustion"-related stays in various asthma wards comes to mind, as does GurneyGate, both the original and the sequel. But the guessing games don't end there. Apparently an actress on the set of Cold Mountain only ate two or three boiled eggs a day (picking between Nicole and Renee is a toughie, since even smushed together they barely fill out one normal person's jeans), and another was so addicted to the gym that she wound up spending her birthday there. Despite the loony techniques, we'd still sleep better at night thinking Britney may be maniacally climbing simulated stairs at Crunch rather than maniacally ordering Cheetos and laxatives at the closest 24-hour pharm.
