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."

The Shannon Twins: 'Tis the Season to Be Naked

Hey, that's just how life goes at the Playboy Mansion. Don't hate the players... or the game, for that matter. Just sit back and enjoy the show.

Why should half-nude pictures and possibly making love to a man four times your age take a break just because it's December 25? Exactly.

Below is Hugh Hefner's annual holiday card. This year's features his new, law-breaking girlfriends: sexy twins Karissa and Kristina Shannon.

Behold, The Shannon Twins nude except for body paint...

Hefner hooked up with the teenage twins after splitting with Girls Next Door stars Holly Madison (now with Criss Angel), Kendra Wilkinson (now engaged to Hank Baskett) and Bridget Marquardt (now MIA, but probably still half-naked).

Hugh Hefner: Excited for Kendra Wilkinson Wedding, Dasha Astafieva Nude

Hugh Hefner is a busy, horny man.

In June, the Playboy founder will be giving away ex-girlfriend Kendra Wilkinson, as she walks down the aisle with fiance Hank Baskett.
"We're going to have Kendra's wedding and reception at the mansion - a spectacular affair!" Hef told Us Weekly over the weekend at the 55th anniversary Playmate celebration in West Hollywood.

Wilkinson will officially move out the Playboy mansion next week.

News of his sexual exploits with Karissa and Kristina Shannon have been well-documented, but sources also say Hef has been getting it on with Ukrainian model Dasha Astafieva. She has a pictorial in the 55th anniversary issue of Playboy.

“Hef is totally smitten with her. She is not his regular type, but Hef says something about her is really doing it for him,” said an insider.
