Tweeting a picture of her cuddled up with Cannon in his hospital bed, feeding him a drink through a straw, the Grammy-winning artist said the situation was “serious” but said he was fighting to recover.
“Please pray for Nick as he’s fighting to recover from a mild kidney failure,” she said in a Twitter message.
The tweet was accompanied by a picture of the couple which showed Cannon wearing a beanie hat, swaddled beneath a pillow.
Elaborating on her website, Carey joked that the situation was a role reversal from last year, when she was in hospital to give birth to their twins.
“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,” she wrote from Aspen, Colorado, where the couple were on holiday when the health scare occurred.
“We’re trying to be as festive as possible under the circumstances but please keep Nick in your thoughts because this is very painful. They tried to kick me out of the hospital but here I am pon de (sic) bed with Mr. C.
And she added: “We’re doing OK but we’re “straaaaaanded in Aspen”. #DramaticDivaPlace (I know, we could be in a lot worse places) but the truth is as long as we’re together, we’re OK.
“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 and Cannon married in the Bahamas in April 2008. It was the second marriage for Carey, whose five-year union to legendary music producer Tony Mottola ended in divorce in 1998.
The singer, 41, has sold 175 million records since the start of her singing career in 1990. She is the third best-selling female artist of all time, according to the Recording Industry Association of America.
