Mariah Carey and hubby Nick Cannon are off to a rocky start in 2012 — the couple's Aspen vacation was cut short when Nick fell ill with a mild case of kidney failure.

The 41-year-old Grammy-winning singer, who just gave birth to fraternal twins last spring, tweeted early this morning that Nick, 31, has been admitted to the hospital and is currently in recovery.

"Please pray for Nick … #mybraveman," she wrote to her five million Twitter followers.

Mariah is taking her "in sickness and in health" vows seriously, refusing to leave her husband's side while he undergoes treatment. "They tried to kick me out of the hospital but here I am pon de bed with Mr. C.," she said on her 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," MC added.

"But the truth is as long as we're together, we're OK … Please keep us and our family in your prayers."

Get well soon, Nick!
