Rumors swirled around the Internet yesterday that Mariah Carey might be pregnant, especially after photos were released of her looking bigger than normal.

Well, Radar Online is confirming that the singer is indeed four months pregnant! Mariah and hubby, Nick Cannon, have yet to make a public announcement about the happy news, but a source says, "Nick has been telling friends how excited he is to be a dad.”

However, Nick is keeping his mouth shut to the media. ""I've said it before and I'll say it time and time again," he said on his radio show on Monday, "when my wife feels like talking about whatever she wants to talk about, you will hear it directly from her."

Mariah was busy performing at a concert in Brazil over the weekend, and although she kept quiet about the big news as well, she did hint at it in a tweet, writing, "Seriously, I really do love it here, beautiful people inside and out! Tonite was tuff 4 me 4 personal reasons, but U got me thru!L4L."

Could those "personal reasons" be the fact that you have a bun in the oven? It must be hard to keep such exciting news a secret! Congrats to the happy couple! (Radar Online)
