Why is Mariah Carey so BIG nowadays? What happened to the "Short Shorts" Mariah Carey??

It's no secret Mariah Carey's gotten pretty plump. So what gives? According to Star magazine, fertility treatments are adding on the extra poundage. A source says, "Mariah wants a baby ASAP. She's actually visited fertility specialists a number of times." Star says Mimi was last spotted leaving a Los Angeles clinic on May 11th and is in the middle of hormone therapy.

Mariah and hubby Nick Cannon have made no secret in the past about their desire to be parents.
