Crystal Harris

If you're the 82-year old owner of the world's most famous men's magazine, you needn't choose between busty young blondes.

You can go to bed with Crystal Harris, Karissa Shannon and Kristina Shannon every night of the week. And we have little doubt that Hugh Hefner does just that.

But if you're a reader of the country's most buzzed about celebrity gossip site, sorry, we're making you take sides in this battle between Playboy bunnies...

With which of Hugh Hefner's girlfriends would you rather go to bed?

Hugh Hefner's latest girlfriend is not a complete unknown. At least not to those that frequent Playboy.com.

While Crystal Harris has never posed naked for the magazine itself (yet), she has bared almost all for its official website.

In fact, the San Diego State University student - under the name "Crystal Carter" - was named the Cyber Club's Coed of the Week for October 30, 2008. Her section of the site even includes a brief Q&A, which we've posted below:

What part of a guy do you study first?
Looks are irrelevant to me because I go for personality first. I never liked jocks or show-offs. Sweet, genuine guys capture my heart and make me smile.

What is your special talent?
I snowboard, can drive a boat and am addicted to frozen yogurt and Nintendo Wii.

We're guessing Hefner and/or the Shannon twins can name a few more talents possessed by Crystal.

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."

Crystal Harris, far right, poses alongside boyfriend Hugh Hefner and his other two new girlfriends, Karissa and Kristina Shannon.

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."
