Nick Cannon Hospitalized; Mariah Carey Asks For Prayers

Mariah Carey has revealed that her husband, 31-year-old singer/actor/comedian Nick Cannon, has been hospitalized for a "mild kidney failure."

The pop superstar posted a picture on Twitter of herself lying next to a somber-looking Cannon in a hospital bed, as well as the message, "Please pray for Nick as he's fighting to recover from a mild kidney failure. #mybraveman." In a longer message on her official web site, Carey explains that the couple is in Aspen, Colo., and that Cannon's treatment has been a "serious moment" for the couple.

"We're trying to be as festive as possible under the circumstances but please keep Nick in your thoughts because this is very painful," she writes. "They tried to kick me out of the hospital but here I am pon de bed with Mr. C."

Carey and Cannon married in April 30, 2008, and exactly three years later, the singer gave birth to twins, Monroe and Moroccan Scott. Carey recently appeared on Justin Bieber's holiday album "Under The Mistletoe," while Cannon told Billboard.com in May that he and Carey were both working on new musical albums.
