Medium star Arquette has filed for divorce from Hung star Thomas Jane, claiming "irreconcilable differences." The couple had a child together in 2003, and were married in the summer of 2006. There was no prenup.

Meanwhile, Ghost Whisperer star Love Hewitt has called off her engagement of a little over a year to Scottish fiancé Ross McCall, People reports:

"They broke up over the holidays and have ended their engagement," says a source close to the couple. "They're both really sad about this. Even their friends are surprised; they seemed really happy. Everyone just wants the best for both of them."

We're saddened by the news on both fronts, but remain confident that once they've worked through the heartbreak, both juggsy clairvoyants will have no trouble recalibrating their ghost-detecting racks to pick up on the frequency of an even more supernatural specter—quality unattached straight guys living in L.A.

Jane, whose real name is Thomas Elliot, was nabbed in Kern County, Calif. by CHP officers. He has been charged with DUI and driving with a blood alcohol level above .08% — both misdemeanors.

CHP tells TMZ Jane was stopped in a late-model Maserati for driving at "an extremely high rate of speed" on I-5. We're told he failed several field sobriety tests, including a breathalyzer. Cops also say he was also driving with a suspended license.

A cooperative Jane was taken to the pokey and he's already out. His arraignment is set for April 9th.

Let Mr. Jane's poor judgment be a cautionary tale for all of you planning on celebrating the ancient Celtic rite of the Drink-'Til-You-Puke Festival: Law enforcement is out in force. As is our custom in these matters, we'll update with a mugshot just as soon as one becomes available; we feel compelled to warn you, however, that Jane's rugged, slightly menacing features should lend themselves well to the medium, producing none of the surprise, awwww-inducing pleasures of, say, celebrity booking photos of toking, castaway gnomes.

Patricia Arquette will soon be taking orders from her little brother.

David Arquette, who's married to "Dirt" actress Courteney Cox, will direct an episode of NBC's drama "Medium."

"I was always a bossy little girl and being David's older sister I've bossed him around quite a bit. Now that he'll be directing me it will be payback time," Patricia Arquette, 38, said Monday.

Hopefully, Arquette's latest directing venture will turn out more smoothly than his last, when he arrived at Comic-Con to preview his "political horror" movie The Tripper, only to accidentally lose the tapes. A repeat of that sort of gaffe might mark an early demise to his fledgling TV directing career, at which point the only sister who'll be able to do anything more is Alexis, who'll sternly warn him in advance that she "really stuck my neck out for you to get this gig running the sound board at Trannieaoke Night at Hamburger Mary's, David, so don't fuck this up."

"It was in a public movie theater, and we were watching Charlie Chaplin's silent film 'Limelight.' The other people in the audience just acted like nothing strange was going on. It turned out that he had rented the theater," [...] "When I saw him on the screen proposing, I said 'Yes! Yes!' He had edited the footage into the movie. I had not suspected a thing. I had no idea . . . I think Thomas Jane is the most romantic man in the world."

Forgive us if that story hasn't just rendered us a shade or two more blush. We must concur with Arquette's assessment: Ignoring for a moment all the surely accidental "Little Tramp" connotations, her paramour's elaborate, Purple Rose of Cairo-inspired proposal lands Jane at the very top of our annual list of Defamer's Least Eligible But Most Romantic Ex-Bachelors, to be toppled only when a certain highly anticipated and overdue bended knee, JumboTron announcement thrills millions with the full-color enormity of its gesture of enduring fake love.

UDPATE: Several readers have written in to tell us that Limelight is in fact a talkie, not a silent picture. Considering the story comes second hand through the Page Six filter, we'll give Arquette the benefit of the doubt in this instance. (Unless of course she was so rapturously in love with her husband/bored with the movie she failed to notice.)
