Valerie Bertinelli said Christina Aguilera shunned her backstage at a Van Halen concert several years ago. In an interview on "Watch What Happens Live" on Wednesday night, November 5, host Andy Cohen asked her about a rumored feud she had with Christina.

The former wife of Van Halen's frontman Eddie Van Halen replied, "No, I didn't have a feud with her." She then clarified the rumor, "I was a fan at that time, a long time ago, and I went up to [Christina] because she was at a Van Halen concert, and I said, 'Oh my God, I think you're a beautiful singer, blah blah blah,' and she just went like [she made an over-her-head motion], 'Yah, whatever.' "

Valerie added, "She gave me the cold shoulder and I thought, 'B***h, I'm a fan! You can't be nice to me?' You know?"

Andy then asked Valerie if she had met the "Moves like Jagger" songstress since. "I have not. She might have gotten better-but I heard she hasn't," the "Hot in Cleveland" actress said.

Valerie previously talked about the encounter during a radio interview in 2008. "I met her, and she was so mean to me," the 54-year-old actress said of Christina at that time, "And I thought, 'You know what? Forget you! I don't need your new album!' What's up with that? She's too young to be blowing people off."
