Here's another piece of Hollywood lore to add to the list of mysteries we'd like to see solved in our lifetime: Did Christina Aguilera say "yeah, whatever" to Valerie Bertinelli at a Van Halen concert that took place somewhere on Planet Earth an indiscernible amount of years ago? Valerie says yes!

On last night's Watch What Happens Live, a viewer—perhaps the disembodied, vengeful spirit of Valerie Bertinelli herself—called in and asked Bertinelli about whether the rumors about the "longstanding feud" between her and Christina Aguilera were true. "I didn't have a feud with her," Bertinelli responded, before going into detail about the origin of her feud with Christina Aguilera, via Page Six:

"I was a fan at that time, a long time ago, and I went up to her because she was at a Van Halen concert."

Bertinelli said she greeted the songstress, 33, with "Oh my God, I think you're a beautiful singer."

But the actress alleged that Aguilera completely brushed her off and said, "Yeah, whatever."

She added that Aguilera "gave [her] the cold shoulder," and she thought, "Bitch, I'm a fan. You can't be nice to me?"

Bitch! Why can't you be nice to Valerie Bertinelli when she tells you that you're a beautiful singer at a Van Halen concert?! Valerie, there isn't anyone out there who can heal your wounds—I know that, believe me—but I do think I know someone who can at least understand.
