Twisted Sisters

Kristina and Karissa Shannon, the blond twins who stole Hugh Hefner’s heart right after the mass exodus of Holly Madison, Kendra Wilkinson and Bridget Marquardt, celebrated their 21st birthdays Oct. 2 at Vanity.

You know how parents of twins dress the kids alike, presumably because they hate their children? The Shannon girls were exactly like that, except instead of matching clothes, they had matching bottles of Grey Goose.

Not matching glasses, mind you. They were pounding straight from the bottles—when they weren’t drinking champagne or doing shots. Hef likes them small, identical and with cast-iron livers, apparently.

The girls were there with their respective men folk. Karissa has been reported to be negotiating the sale of a sex tape to Vivid with boyfriend Sam Jones III of Smallville. The whole twin thing must have her used to doing everything in twos, though, because she’s also supposed to be Heidi Montag’s playmate in the girl-on-girl scene from that rumored tape.

We were wrong. Hef likes them small, identical, with cast-iron livers and terrible taste in women.
