'All I Want For Christmas Is You' icon Mariah Carey has confessed that the only way she would consider adding to her family is if her husband could physically carry a baby.

She has twins Moroccan and Monroe with Nick Cannon, but told 'Watch What Happens Live' that she probably won't be aiming to give them any other siblings because pregnancy was such a difficult time for her:

"I had pre-eclampsia, I had gestational diabetes. [It was] a really difficult pregnancy and I was alone most of the time... we love Nick, but he was working! He's the hardest working man in showbusiness."

"If Nick could have the babies himself, then maybe. Then, bring 'em on. We love kids!"

Carey added that having children has changed her outlook on life, especially where her career is concerned: "I'm responsible for these children 'til forever so I look at it like, they didn't ask for this lifestyle. Here they are, and it is so different than being able to just be like, 'OK, bye, well, I'm going here now. I just did a show, I'm leaving.'"
