Playboy's nude request for Cindy

The former Supermodel has turned down the offer to pose again for the mag - reckoning that now her son, Presley, is five it wouldn't be proper.

Third time is clearly not considered lucky but just gratuitous for the 38-year-old mother of two after she politely declined their third offer to appear in the buff, reports the Daily Mail.

Cindy last appeared in the men's mag back in 1999 - before she became a mother - and is now of the opinion that it's not worth her son getting a ribbing from his mates in the playground:

"Now that I have kids it's different. My son's five and he's not quite aware yet, but I wouldn't want him to get hassled," she said.

"Herb Ritts, the photographer I did it with both times, has passed away and I don't know if I would trust anyone else."

Cindy, once married to Richard Gere, is now married to Rande Gerber and was the first Supermodel to appear in Playboy.

According to IMDb.com she said: "I think they should have been cast in bronze at some point because there's been so mush hysteria surrounding them.

"I suppose you could have worse compliments, but you don't want to get stuck in people's minds just for having a nice story.

"It's a contradiction because being attractive is a way of getting recognition and it can lead to a lot of work, but at some point you've got to convince people that you can do more than just play a sultry female fatale kind of character."
