Catty Christina Aguilera

Vegas is for losers, laughs Christina Aguilera — and Jennifer Lopez, Britney Spears and Mariah Carey aren’t happy!

The diva disaster started when Christina’s manager, Irving Azoff, said she wouldn’t join Britney, Mariah and J.Lo in doing a greatest-hits show in Vegas, because his client “hadn’t peaked yet” and is “in the prime of her career.”

“Christina will have to do some damage control, but she’s not mad at Irving,” an insider told The National ENQUIRER. “She said, ‘I won a Grammy this year! Why would I go to Vegas and join Britney and Mariah in being an oldies act?’”

The 34-year-old pop diva — who hasn’t released an album since 2012 — likes working less, too!

“I don’t have to spend three nights a week reliving the past,” Christina scoffed. “I’d get more fans doing a season of ‘The Voice!’”
