DENISE RICHARDS TAKES IT OFF — SO SHE CAN TAKE IT ALL OFF FOR PLAYBOY

RED-HOT mama Denise Richards is preparing to bare all for Playboy, only three months after giving birth — and her hubby Charlie Sheen couldn’t be more proud!

“Denise is thrilled that Playboy approached her to model in the magazine so soon after she became a mom,” said an insider. “She thinks it’s an incredible honor.

“And she said that Charlie isn’t at all jealous. In fact, he’s really proud of her and happy that she wants to show off her beautiful body to other men.”

But Denise, who has starred on TV’s “Spin City” and in movies, is nervous about losing her baby fat in time for the photo shoot, say pals. She’s hoping to be in Playboy’s December issue and the photos have to be completed several months in advance.

LOOK HER BEST

“Right now she’s dieting and exercising like crazy so that she’ll look her best for the camera,” said the insider. “She’s working with a personal trainer and following her own diet.

“Already she looks in tip-top shape. But that’s not good enough for Denise. She wants to be absolutely perfect when she strips in front of the world.”

Denise, 33, whose husband Charlie stars on TV’s “Two and a Half Men,” gave birth to the couple’s first child, a daughter Sam, on March 9.

“Denise was thrilled when Sam was born. Becoming a mother was something she always dreamed of,” said the insider.

VETO POWER

“She said that she’s not doing full nudity out of respect to her daughter and other children she might have. And she says she has veto power over the pictures that will appear in the magazine.

“She wants everything to be perfect. Her second big dream is being fulfilled. Appearing in Playboy is something she’s always wanted to do, too.” — PATRICIA TOWLE and TIM PLANT
