Today, Mariah Carey continued to share her baby joy with her fans by tweeting a picture of her baby bump. It's actually much more than a bump, considering Carey, who turned 42 yesterday, is carrying twins!

In the picture, Mrs. Nick Cannon wrote 'dem babies' and painted a colorful butterfly on her tummy, which has been one of her favorite symbols since her first days as a performer. Along with the picture, Carey wrote, "My attempt @ festiveness on 327! For ATLITL thank u + I♥U! Comin soon #dembabies! LYMA+thanx 4 making me happy:)."

Both Carey and her hubby Nick Cannon seem excited about the big day, but daddy-to-be Nick Cannon also seems nervous, since he has been psyching himself up via Twitter for the past couple of days. Last Thursday, he tweeted, "People listening @923nowfm are trying to give me advice for when that day comes. I'm trying to prepare but I get queezy in Hospitals LOL."

Carey, who experienced some false-alarm contractions over the weekend, is expected to deliver the twins in just a few short weeks. Stay tuned with PopCrush for more baby updates!
