Mariah Carey is terrified of losing her ass.

The pop diva says although she likes working out she can't exercise too much in case she loses her ample butt.

She told Britain's Daily Mirror newspaper: "I've been working out like mad - you can even punch me in the stomach and feel how tight that is.

"But I've gotta slow it down because the other day someone told me I was losing my ass - and I don't want to lose that."

And despite partying until 6am with the 3AM girls, the multi-Grammy-award-winning babe's beloved dog Jack was never far from her mind.

"He's waiting for me in the let, as we're flying to Paris to shoot the video for may new song Say Something."

Meanwhile, Mariah has been hotly-tipped to star in new movie 'Tennessee' - despite being lambasted for being a bad actress.

"Everyone said I was fat, so I did something about it," songbird Mariah Carey blurted to Page Six, seemingly out of nowhere.

"Here! Feel my thighs! Feel my butt!"

After several requests, Page Six agreed to fondle her newly firmed physique, and can confirm the absence of unsightly "jelly."

"See?" Carey said, proudly. "I'll never be a stick woman, but now I'm fierce!"
