Considering Mariah Carey's spent the last decade or so rocking spandex microdresses, if the pop star happened to be pregnant -- or even, say, ate three M&Ms for lunch -- the world would take notice.

Lately, it’s been rumoured that newlywed Carey has got a mini-MiMi on the way. So when the pop star took Ellen DeGeneres' couch for today's episode, DeGeneres tried her best to get the scoop from Carey herself.

Carey shut down DeGeneres' point-blank suggestion that she might be preggers. But hey, as we've all learned from those recent Angelina Jolie baby rumours, the surest way to tell if a celeb's got a multimillion dollar cover story payday coming their way (er, baby on board) is if they're not drunk off their toned asses.

DeGeneres told Carey it's cool if she doesn't want to dish on her reproductive status -- but she did pull out a bottle of champagne, which she offered to share with the singer.

Carey, however, would have none of it. "It's just fattening," was Carey's excuse. "I can't believe you did this to me Ellen. ... This is peer pressure."

DeGeneres, still goading Carey to take a sip, then suggested "let's toast to you not being pregnant."

"Oh, my goodness," replied Carey. "I can't believe her! Why would we toast to that? How about to the future."

Carey then accepted a glass, only to pretend to drink the champagne, once again making excuses by saying "It's too early for me. I only drink after 3 p.m."

"You're pregnant," DeGeneres said -- basically confirming what everyone watching this charade was thinking, but only further flustering Carey.

"I didn't say that. No, no, no. My mother would be at home, like on the computer, like what are you talking about?" said Carey. "We will let you know when we're going to have a family."
