Mariah Carey celebrated her birthday with a trip to the hospital.
Carey, who's pregnant with twins, was hospitalized late Saturday after having contractions, but she was released the next day.
In December, Carey's husband Nick Cannon announced that the couple was expecting twins —a boy and a girl. Carey is due next month.
"They almost came on 3/27- happy anniversary indeed!!!" Carey added. "We have a few more weeks 2 go but- wow!!!: ) #soreadyallready!"
