Mariah Carey can't wait to pop out her twins – but she also really seems to be enjoying her pregnancy.

Just one day after Tweeting a post – with a happy face – about contractions that sent her briefly to the hospital on her birthday, the singer, 42, posted a photo of a huge butterfly painted on her baby bump with the words "dem babies" written above the image.

"My attempt @ festiveness on 327!" she Tweeted Monday. "Comin soon #dembabies! LYMA+thanx 4 making me happy:)."

In her original Tweet on Sunday, Carey wrote: "[The babies] almost came on 3/27 … We have a few more weeks 2 go but- wow!!!: )."

Her hubby Nick Cannon, 30, praised his leading lady, Tweeting, "[Women] are the ones that have to be the strongest in the whole ordeal! I am in awe of my wife!"
