mariahbackhome230.jpg Mariah Carey is resting at home after a trip to the hospital early Sunday morning. The singer tweeted a few hours ago, "really wanted 2 celebrate w/us/share the anniversary! I started having contractions last night..went 2 the hospital."

Carey, who turns 42 today, added, "They almost came on 3/27- happy anniversary in deed!!! We have a few more weeks 2 go but- wow!!!: )"

So how has hubby Nick Cannon been handling the whole ordeal? Last week he joked on Twitter, "I am probably going to faint in the delivery room! I need to man up! Or maybe I should say WOMAN UP since they are the ones that have to be the strongest in the whole ordeal! I am in awe of my wife!"
