The 'Dreamlover' singer - who welcomed twins Monroe and Moroccan into the world on April 30 - and her husband Nick Cannon have been disagreeing about whether or not to expand their family further, but the 41-year-old star is adamant two kids is enough.

Asked if he wanted to have more children, Nick told In Touch magazine:

"I do, Mariah doesn't! She was like, 'That's it, I'm done! Two at once!'

"It was an intense pregnancy to carry twins around. She was a trooper.

She's feeling amazing now. She's back on her feet doing her thing."

Despite the showbiz background of both their parents, TV presenter Nick is insistent they should try a different career path when they grow up.

He added: "There are so many other aspiring things to be in life. I always think we put too much emphasis on the entertainment world. I would love it if my children were doctors."

'America's Got Talent' front-man Nick finds fatherhood easy because he doesn't need to sleep.

He joked: "I never slept before! I'm kind of cut out for fatherhood because I never sleep. So now, instead of doing other stuff, I'm with my kids. Other than that, definitely more sensitive to my moves because I'm responsible for people now."
