Paris Hilton is at the Sundance Film Festival in Park City, Utah this week, and she’s skanking up the town just as much as you’d expect. Paris is incapable of going anywhere or doing anything without bringing a lot of unnecessary drama with her. And Sundance is no exception. While there, she’s ditched her supposed BFF Brittany Flickinger multiple times to hang out with former Danity Kane singer Aubrey O’Day, resulting in hysterics from Flickinger. Oh, and also made out with one of the less famous MySpace CEOs. Something tells me that won’t help their flailing business.

Paris Hilton, who seems to have no interest at all in movies, is even being shunned by her sister. “Nicky can’t stand Paris’ new BFF,” said one source – meaning Brittany Flickinger, who won Paris’ reality-show contest on MTV, “My New BFF.”

Nicky forbade Paris from staying at Jeffrey Katzenberg’s house with her, forcing the heir-head to rent a condo and befriend Danity Kane singer Aubrey O’Day.

“Paris kept ditching Brittany for Aubrey,” said our source. Friday night, the two left Flickinger at the Eldridge and went across the street to Tao, where the former Best Friend Forever found them at 2 a.m. “She was crying and screaming, ‘Paris, stop leaving me!’ ” said our snitch.

Sunday, Flickinger was spotted snapping up freebies at the Owl’s Lab gifting station, while Paris hung out with MySpace CEO Chris DeWolfe at the MySpace Cafe. They were later seen sucking face at a party. A rep for MySpace said, “We don’t comment on executives’ personal lives.”

I can’t help but wonder if Chris DeWolfe thought being connected to Paris would somehow bring MySpace a little much-needed attention, since hardly anyone’s using it and most people have migrated over to Facebook instead. If he isn’t smart enough to be afraid of Paris’ myriad sexual diseases, it’s no wonder his business sense isn’t that great either.
