{blackbabes} Mariah Carey Preggers-and the J.Lo Connection!

If Mariah Carey's feeling emotions, it's probably because of that baby she's carrying.

A source confirms to E! News that the 40-year-old pop star is pregnant with her and hubby Nick Cannon's first child after undergoing in vitro fertilization at a Beverly Hills clinic.

It's a good thing Cannon thinks Mimi is going to be a great mommy.

Our Carey source says that the five-time Grammy winner is being treated at the Southern California Reproductive Center—the same clinic, the source says, where Jennifer Lopez received care while expecting twins Max and Emme.

Of course, Carey could have practically given birth twice over during the span in which she's been rumored to be pregnant.

Bumpwatch really focused on the "Hero" singer when Cannon touted a big announcement (their dog was having puppies) and then again when she was spotted in August wearing a maternity dress. And then again when she was photographed at LAX in a wheelchair (stiletto = twisted ankle).

Plus, if she ever gained an ounce...look out.

Her rep declined to comment.

But now the world is free to embrace Carey's belly with open arms. Congrats to the expectant parents!
