Crystal Harris Claims Her Piece of Hugh Hefner

Move over, Karissa and Kristina Shannon.

Crystal Harris wants to make her presence as Hugh Hefner's third new girlfriend known!

The 22-year old busty blonde revealed on E! Online’s message board that she's moved into the Playboy mansion alongside the aforementioned twins.

“Hef gave me permission to fill people in on the new updates as a voice from the mansion,” Harris wrote, adding that only only her and the Shannons have replaced Holly Madison, Bridget Marquardt and Kendra Wilkinson so far, though “there are a couple [other girls] that we have interest in."

As for details about Harris: she's a psychology student at San Diego State University. Her MySpace page paints her as a passionate romantic that loves a good cliche as much as a wrinkle-laden roll in the sack:

"I believe in opening your heart and letting your walls down, it is better to have loved and lost, than to never have loved at all."
