Paris Hilton — UNBANNED From Las Vegas Hotel

Paris Hilton‘s war with Vegas titan Steve Wynn has apparently come to an end … because she partied her face off at one of his nightclubs last night … 15 months after she was banned from the property.

TMZ has obtained photos of Hilton getting down and dirty inside Surrender nightclub at Wynn’s ultra-swanky Encore hotel in Vegas last night.

Paris had been blackballed from all things Wynn back in August 2010 — after she was arrested for cocaine possession as she arrived to The Wynn hotel.

Paris has since completed her legal obligations — now, it seems she’s made good with Wynn, too.

9:55 AM — A rep for Wynn just made it official — telling us, “Paris is welcome on the Wynn properties now.”
