'I had a difficult pregnancy and was alone most of the time': Mariah Carey on why she won't have more children with Nick Cannon

Mariah Carey has revealed her difficult first pregnancy has put her off having more children.

The Art of Letting Go singer, 43, had such a tough and lonely time while carrying the couple's two-year-old twins, Moroccan and Monroe, she wouldn't want to put herself through that experience again.

'I had pre-eclampsia, I had gestational diabetes,' she said on US talk show Watch, What Happens Live, on Sunday.

Jokester: Mariah Carey appeared on Bravo's Watch What Happens Live show on Sunday night, saying she would only have more kids if her husband Nick Cannon could carry them

Grueling nine months: The 43-year-old singer said she had a very difficult pregnancy, suffering from pre-eclampsia and 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 show business.'

She joked that if her husband could carry a baby, she would love to expand her brood.

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

Once the jokes subsided, however, the diva claimed she was more than happy with her family and feels content with her two children.

She added: 'Nick and I have a boy and a girl, I couldn't ask for better.'

More children? The Hero singer quipped on the show - 'If Nick could have the babies himself, then maybe. Then, bring 'em on. We love kids!'

The We Belong Together hit maker also revealed that having children has changed her outlook on her career. She makes decisions based on her kids' needs.

'I'm responsible for these children 'til forever so I look at it like, they didn't ask for this lifestyle,' Mariah said.

'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."'

(The couple have been recently hit by rumours of marital strife, but have been posting happy pictures from their family holiday in Aspen over the weekend.)

Mariah had an eventful year as a judge on American Idol but quit the show in May following her famed feud with fellow panellist, Nicki Minaj.

The singer, who recently described her Idol experience as being akin to hell, insisted she'll never be a reality show judge again after feeling duped by the show's producers, who changed the judging panel from three people to four after signing her up to a reported $18 million deal.

Mariah said: '[They said], "It'll be a three-person panel" ... the typical thing. And then, they tie me up with this; it was [a] typical showbiz twirl the moustache moment. I'm not blaming anybody.

'This is a disclaimer - this is not about anyone in particular - I wouldn't have done the show had I known that they were doing a total experiment village moment and I get to be the person who's out in front. It wasn't my bag.'
