Jenny McCarthy has revealed that she once sent her 10-year-old son's dentist a naked picture of herself.

The former Playboy model, who will be appearing in a new spread soon, told Wendy Williams that she accidentally sent the saucy photo to the embarrassment of her 10-year-old, Evan.

The blonde beauty, who had a five-year relationship with Jim Carrey, regaled the talk show crowd with the funny story.

"It's horrific to remember," she said. "Evan woke up and was like, There's this weird thing on my gum.' I saw this abscess sticking out from his gum and I was like, Oh my gosh, that's disgusting!'

"So I called the dentist and I was like, This is insane.' He's like, Take a picture and send it to me.'

"I went to the bathroom and I was shoving my iPhone in his mouth. I'm taking a picture of it and I'm sending it to the dentist and I sent him a nude on accident! I swear to God!"

The self-portrait had originally been snapped for her new boyfriend, Chicago Bears linebacker Brian Urlacher, who she has been dating for a few months.

"The dentist is like, 80-year-old," she laughed. "I literally screamed at the top of my lungs. Is there an app? Like Uh-oh! I Effed Up!'"
