Nick Cannon on nude pictures with Mariah Carey: "It's a little weird"

(CBS) Nick Cannon has revealed that he and pregnant wife Mariah Carey recently posed in the buff together for a series of artistic photos that will be displayed at their house.

But now the "America's Got Talent" host says he is not too sure if it was the best decision.

"My children are going to have to see these pictures," Cannon said on his radio show "Rollin' with Nick Cannon" Tuesday, according to People. "It's a little weird."

"It's a little nasty," he adds. "I mean, have you ever seen your parents naked?"

The couple, who tied the knot in April 2008, are expecting twins - a boy and a girl. Their official due date is May 15, Cannon confirmed to the Los Angeles Times.

"When they get older and their friends come over, they will see the pictures and say, 'Your daddy's butt naked,'" he said.

And while Cannon, 30, may be having second thoughts, Carey, 42, seems to not mind artfully displaying her pregnant body.

The mother-to-be recently flaunted her baby bump while baring it all for a Life & Style cover shoot.

"I was feeling very vulnerable about taking pictures at all right now, but then I didn't want to miss this opportunity to document this once-in-a-lifetime experience," she told the magazine. "My ultimate goal was to share this incredibly personal moment with my true fans."
