Anna Faris Will Pose on Cover of Playboy Magazine

Faris won`t strip off completely as she still wants to appeal to the movie`s young fans.

The 'Scary Movie' star will appear in the legendary magazine to coincide with the release of her movie 'The House Bunny'. However, Anna - who stars as a Playmate who has to fend for herself after she is thrown out of the Playboy Mansion - won't strip off completely as she still wants to appeal to the movie's young fans.

Rumer Willis, Katherine McPhee, Colin Hanks and Beverly D'Angelo will also appear in the film, along with Playboy founder Hugh Hefner.

It was recently revealed Pamela Anderson performed a naked birthday dance for Hefner when he turned 82 on April 9. The former 'Baywatch' actress surprised the magazine mogul by walking into his luxury suite at Las Vegas' Palms Fantasy Towers hotel wearing just a pair of high heeled shoes.

Pamela - who has graced the cover of Playboy 12 times - then performed a steamy lapdance as a birthday treat. Palms owner George Maloof revealed: "He was stunned. He had the biggest smile I have ever seen."
