The 39-year-old blonde beauty will feature on the July/August cover of the famous men's magazine after agreeing to shoot a naked pictorial almost 20 years since the first time she appeared in the men's magazine's pages.

Jenny can't wait to bare all in Hugh Hefner's publication again and is doing it for all the world's "MILFS" - a slang phrase for attractive older women.

She wrote on her twitter page: "My comment on posing for Playboy: Why should only 20 yr olds be considered sexy? Let's here it for the MILFs. (sic)"

The 'Scary Movie 3' star - who has a nine-year-old son Evan - began her career with a shoot in Playboy's October 1993 issue and she went onto to be named Playmate of the Month and later Playmate of the Year.

She has gone on to appear in the magazine several times.

Jenny turns 40 in November and previously admitted she wanted to pose naked in the title one more time before she reached the landmark age.

She said: "I would absolutely pose for Playboy. I would be so flattered if they asked me. It's probably not going to happen but I think I want to do it again."
