Pregnant singer Mariah Carey and her actor husband Nick Cannon have posed together nude in a series of photos which they plan to put up on the walls of their home.

Carey, 42, is due with twins on May 14. But Cannon, 30, confessed he is not so sure it was a wise decision, reports usmagazine.com.

"My children are going to have to see these pictures... It's a little weird. When they get older and their friends come over... they will see the pictures and say, ‘Your daddy's butt naked,'" he said.
