Hugh Hefner Introduces New Girlfriend Number 3

Hugh Hefner has another new girlfriend. The 82-year-old Playboy founder - who split with former girlfriends, "The Girls Next Door" stars Holly Madison, Bridget Marquardt and Kendra Wilkinson last October - has moved 22-year-old Crystal Harris into the Playboy Mansion.

Crystal - who describes herself as a "good girl" who likes "the rain, the seasons and fast cars" on her MySpace page - shares the aging lothario with 19-year-old twins Karissa and Kristina Shannon.

The newest member of the Playboy family introduced herself to the public on an internet message board over the festive season.

Crystal wrote: "Hef' gave me permission to fill people in on the new updates as a voice from the mansion. No other girlfriends are in the mix at this time but there are a couple that we have interest in. As for now, it is just us three."

The platinum-blonde beauty was first photographed with Hugh and the twins in October, soon after former girlfriend Holly announced she was moving out.

She has yet to pose for Playboy, but has appeared semi-nude on the magazine's website.

It is not known whether Hugh's new bevy of beauties will appear in the next season of hit series "The Girls Next Door."
