Kate Moss is commemorating her big 40 by stripping down to her birthday suit for Playboy's January/February double issue.

She turns 40 in January.

While going full frontal is nothing new for the British supermodel, her gracing the cover of the magazine is novel, considering Moss is famous for her waifish figure and is certainly not the typical blonde buxom Playboy bombshell.

Playboy founder Hugh Hefner felt that it was "natural" for Moss to be their cover girl.

He told Los Angeles Times: "Moss is a worldwide celebrity and iconic, and crosses the boundaries from sexual imagery to upscale modelling."
