Paris Hilton just can’t take a hint. After Sundance founder Robert Redford dissed the party girl as the very reason his festival is “not as fun” anymore, Paris hit Park City, snapping up swag and dancing the nights away. “I love Park City!” undeterred Hilton tweeted Saturday before heading to the pop-up of Las Vegas club XS with her 21-year-old boy toy River Viiperi to see DJ Avicii. A night earlier Hilton made the rounds with Viiperi, her brother Baron and his gal pal Vanessa Dubasso at the Saygus Everest Mansion — where spies say she snapped up a Saygus Vphone, Bravon speakers and a Dell computer. The group then headed to Tao at Sundance’s Village at the Lift till the wee hours. Hilton then returned on Saturday night to the Everest spot, “in full-on diva mode,” said a spy. “She was wearing sunglasses and acting like, ‘I run this place.’ ” Redford quipped last week of Sundance’s transformation from indie fest to celeb circuit stop: “Pretty soon you had Paris Hilton, and she didn’t have anything to do with the films. I said, ‘What movie is she in?’ ”
