Mariah Carey's hubby Nick Cannon hospitalised with kidney failure

Mariah Carey's husband Nick Cannon has been hospitalised after being diagnosed with "mild kidney failure".

Cannon is spending the first week of the New Year in hospital in the Colorado ski resort of Aspen, where he and his wife usually spend Christmas.

Carey informed about her hubby's illness on twitter, the Telegraph reported.

The 41-year-old posted a picture on her website of a miserable looking Cannon in a hospital bed as she lay beside him.

She asked for prayers and said Cannon's situation was "very painful."

She later called it a "serious moment that's very tough on all of us."
