Paris Parties in Park City

Looks like "old" Paris is back for good! She arrived in Park City, Utah for the Sundance Film Festival last night, and immediately took to partying the night away. Utah's not ready for this!

The glittery heiress made a quick dash to her waiting SUV after getting her groove on inside the Stereo NYC Lounge. The Festival is the "it" hub for all celebs for the past few days -- it's looking a lot like the streets of L.A. Holy DUI!
