Nick Cannon is in the hospital recovering from a "mild kidney failure," according to wife Mariah Carey.
On January 4, Carey took to her Twitter page to announce that her husband was in the hospital.
"Please pray for Nick as he's fighting to recover from a mild kidney failure. #mybraveman," Carey Tweeted on her official Twitter page.
The singer also took to her official website to go into deeper detail about the situation, and ask for prayers and support from her fans.
"This is us in the hospital - role reversal," Carey wrote on her official website. "Last year it was me attached to the machines (after having dembabies) and Nick was there with me through it, and now here we are."
"We're trying to be as festive as possible under the circumstances but please keep Nick in your thoughts because this is very painful," the songstress continued. "They tried to kick me out of the hospital but here I am pon de bed with Mr. C. ... 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 so please keep us and our family in your prayers."
Carey, 41, and her husband Cannon, 31, wed in April 2009. Cannon is known for his role as the host of "America's Got Talent." The pair became parents to healthy twins Monroe and Moroccan, who also go by "Roc and Roe," in April 2011 via Caesarean section. The date also marked the couple's second wedding anniversary. The already famous twin babies even have their own website, dembabies.com, where fans can sneak a peek at personal photos of the family.
Carey and Cannon debuted the twins in October on "20/20," where they also discussed their high-risk pregnancy.
Though the couple are joyful parents now, the process of conceiving was fraught with difficulties, including a miscarriage. With the help of fertility treatments, the couple welcomed their healthy twins.
"I don't think I understood the enormity or the magnitude of what it really does to your body," the Grammy-winning singer said in a promo for the episode. "Like it's not just, oh you don't look pretty and you have a bump."
Carey debuted a slim figure in November, becoming the face of the Jenny Craig diet program. She also showed off her curves in the December debut of the revamped "All I Want For Christmas" video, which featured Justin Bieber.
