Mariah Carey: Battle to Be Slim for X Factor Premier

Mariah Carey is on a mission. The chart-topper, who gave birth to twins Monroe and Moroccan on April 30, is desperate to shed her final 25 lbs. of baby weight before she returns to the spotlight on the Sept. 21 premiere of Simon Cowell’s The X Factor.

“Mariah has been careful in her few public appearances to hide her extra pounds,” an insider says of the star, who was able to drop about 30 lbs. within a few months.
“She knows everyone is curious about how she’s rebounded after her pregnancy. She wants to have a killer body!”
So Mariah, 41, has hired a trainer and nutritionist to oversee her diet and exercise program, which includes using free weights, swimming and doing aqua aerobics.
“She works out a minimum of two hours a day, seven days a week now, and she’s on a spartan diet, cutting out refined sugar and white flour and most meat products,” says the insider.
“It’s making her crabby. But she’s leaving nothing to chance!”
