Mariah Carey is delighted her family is finally home together again.

The singer's husband Nick Cannon was hospitalised with "mild kidney failure" while they were in Aspen, Colorado, last week.

He has now been released from medical care and is back home with Mariah and their twins Monroe and Moroccan, something she is thrilled about.

"Daddy Nick is getting better, we're all home together taking care of each other, excited about the new year !!" she wrote on Twitter.

Nick was transferred to a Los Angeles hospital last week, where it's thought he had surgery.

Yesterday, his representative confirmed he had been allowed home and said he was "resting and recovering". He is due to return to his radio show on January 17.

Mariah has kept fans updated on her husband's progress throughout his illness, even posting a picture of her snuggling up to him on his hospital bed.

She seems relaxed about his prognosis now and even found the time to take the twins who were born in April swimming this week.

"Took dembabies swimming yesterday. classic! Roc thinks he's Jacques Cousteau... I'm gonna call him Roc Cousteau. :)," she wrote.
