Nick Cannon is having second thoughts about he and his wife Mariah Carey taking nude photos together.

Carey, who is due to give birth to twins very soon, posed for the artistic flicks with her hubby of nearly three years, to commemorate the pregnancy. "My children are going to have to see these pictures," Cannon said on his radio show. "It's a little weird. It's a little nasty. I mean, have you ever seen your parents naked? When they get older and their friends come over they will see the pictures and say, 'Your daddy's butt naked.'"

Carey may not feel the same, seeing as how she's been very open about exposing her baby bump both on her Twitter page, and in the latest issue of Life & Style magazine. The photos feature the nude singer in various shots, covered only by her hair in one shot, and a strategically placed blanket in another.

"I was feeling very vulnerable about taking pictures at all right now," she told the magazine. "But then I didn't want to miss this opportunity to document this once-in-a-lifetime experience."

The couple married in a secret ceremony in the Bahamas in 2008. They are scheduled to welcome a baby boy and baby girl sometime in the next few weeks. Mariah Carey's revealing magazine spread, baby bump included, will hit stands on Friday (April 8).
