Mariah Carey wheeled out of hospital

Show Caption

Mariah Carey exited the hospital in usual diva fashion — air kissing hospital nurses and vowing the show will go on.

"Well, that was fun," she said before getting in to a car.

The singer has her sling in place after hurting her shoulder Sunday while shooting a music video. She thanked fans on Twitter for well-wishes, saying: "Still in a lot of pain - cracked rib, fractured shoulder, bruises everywhere, but the show must go on."

She's scheduled to perform Saturday with the New York Philharmonic in Central Park for a Hurricane Sandy benefit.
