Mariah Focused On Getting Knockout Bod Back, Says Hubby

She only gave birth to twins four months ago, but Mariah Carey is determined to get back into pre-pregnancy shape.

Hubby Nick Cannon told Us Magazine that she's been hard at work in the gym. "She's so focused right now on every aspect," he said. "She's going to come back and knock out the world. She's getting in shape."

Apparently the 41-year-old singer doesn't just want to be fit, she wants to look as skinny as she did twenty years ago! Nick, 30, told the mag:

"At two months she was walking around in a bathing suit. Every day she's just killing it. I personally think she's going to come out looking better -- looking like it's 1990! I think that's what she's aiming for, and I think she'll reach that goal."

Good luck, Mariah!
