Mariah Carey and Nick Cannon

Mariah Carey almost got two surprises on her birthday. The pregnant diva thought she was going into early labor with her twins over the weekend, but it was only a false alarm.

Mimi was rushed to the hospital on the eve of her birthday, thinking that her twins were coming sooner than expected. “So #dembabies really wanted 2 celebrate w/us/share the anniversary! I started having contractions last night..went 2 the hospital,” she shared on Twitter.

But despite the labor pains, Mariah and Nick’s babies will wait to make their grand entrance. “Finally they said I could come home after they got it under control but they almost came on 3/27- happy anniversary in deed!!! We have a few more weeks 2 go but- wow!!!: ) #soreadyallready!”

The couple is expecting a boy and a girl in late April. Mariah celebrated her 41st birthday, or “anniversary” as she calls it, on Saturday.
