Nick Cannon is suffering from mild kidney failure.  And his wife Mariah tweeted a pic of him in a hospital bed getting nursed back to health.  Details inside...

MiMi asked her followers for prayers this morning as her 31-year-old hubby recovers from a health scare in Aspen.  She said:

Please pray for Nick as he's fighting to recover from a mild kidney failure. #mybraveman

And in the pic, MiMi is in her pajamas in Nick's hospital bed with him nursing him back to health.  She also put a statement on her website about it explaining:

This is us in the hospital - role reversal; 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. They tried to kick me out of the hospital but here I am pon de bed with Mr. C.

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. LYM.'

Nick was the jack of all trades in 2011 as he hosted his own radio morning show in L.A., hosted "America's Got Talent," performed his duties as Chair of Teen Nick, performed DJ gigs around the country, is Daddy to 2 brand new babies, and continued doing weekly stand-up around the country.  Sounds like it's time for a break Nick.  Get well soon!

The twosome spent the Holidays in Aspen with their twins Roc & Roe.
