While we're used to seeing celebs posting snogging, eating, partying snaps on the social networking site, we think we've seen it all after the US songstress uploaded the rather private poorly snap of her other half.
She added the description: "Please pray for Nick as he's fighting to recover from a mild kidney failure. #mybraveman".
The image shows Nick flat out in bed with a bobble hat on (they're currently in plush ski resort Aspen) with Mariah lying next to him feeding him a drink in a pair of tartan PJs.
She posted more info on the illness on her website, explaining that the pair have been stranded on hols.
She wrote: "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."
Wishing Nick better!
