GET out of Sundance!” That’s what Robert Redford, founder of the Sundance Film Festival, told reality TV party monster Paris Hilton after she crashed his annual fete yet again, say sources.

“She didn’t have anything to do with the films,” an irritated Redford, 75, groused to a reporter.

What movie is she in? She and her hard-partying, swag-grabbing cohorts have made the festival not much fun. There are too many people who come to the festival to leverage their own self-interest.”

The Oscar-winning screen legend – star of such classics as “The Sting,” “The Way We Were” and “Butch Cassidy and the Sundance Kid” – founded the Park City, Utah, film festival in 1978.

But Paris, 31, has turned the highly regarded independent movie showcase into a Spring Break-like pilgrimage for the past few years, and the 2013 event was more of the same.

The jet-setting socialite, famous for her pornographic sex tape “1 Night in Paris,” showed up with her latest boy toy, 21-year-old model River Viiperi.

She hit all the hottest clubs and snatched pricey swag, including designer duds and the latest electronic gadgets that vendors give celebrities for free, says a source.

“Paris doesn’t come to Sun­dance for the movies,” a festival regular told The ENQUIRER. “She’s here to pose, party and get stuff for free. This year was no different – she boozed it up, loaded up on gifts and went home richer than she came.

“Her 15 minutes of fame expired a long time ago, and we’re glad Robert Redford blasted her. She’s considered a joke here.”
