Paris Hilton.

PARK CITY, Utah - Was a blizzard going to stop stars from going out Saturday night? Of course not. Sundance's historically most hectic night lived up to its reputation, with Aziz Ansari and Drake rocking out a packed house at Bing bar (even though the rapper's plane arrived six hours late and he "almost lost my life six times" trying to get here).  The Roots' ?uestlove spun at the Compound where he debuted his line of fried chicken to the masses. "I just really wanted to make the kind of chicken that you'd line up for after a music festival at 3 a.m., you know?" he told ABCNews.com. "We're hoping to do food trucks next."

Up Main Street at the House of Party Rock, LMFAO blew it out. At the T-Mobile/Google Music lounge, Paris Hilton took the stage to rev up the crowd with DJ Kaskade. After the bars closed, private house parties were the place to be. Hilton showed up at the home of producer John Flanagan at the ripe old hour of 5 a.m.
