Nick Cannon is on the mend after suffering a "mild kidney failure," the 31-year-old's wife Mariah Carey announced via Twitter Wednesday.
Carey, 41, also uploaded a photo of herself with Cannon from inside his Aspen, Colorado hospital room.
"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 wrote on her official website, adding that doctors tried -- and failed -- to remove her from Cannon's room.
"I'm not trying to make light out of the situation because it's a serious moment that's very tough on all of us," Carey, mother to twins Moroccan and Monroe, wrote. "So please keep us and our family in your prayers."
