Paris Hilton and Her BFF: Park City Princesses

Trying to fit in as much as she possibly can while staying in Park City, Paris Hilton was out for a night of fun while taking part in the 2009 Sundance Film Festival festivities on Saturday (January 17).

Accompanied by her BFF Brittany Flickinger, the hotel heiress was decked out in a black dress with a leopard fur coat overtop paired with a matching headband and shoes.

The girls made three stops throughout the course of their outing, as they attended a birthday dinner for Scott Lazerson at The Green Lodge, dropped in on 50 Cent's Sundance Party and mingled with the likes of Ashton Kutcher and Demi Moore at the "Spread" premiere afterparty.

Also in town for Sundance is Miss Hilton's sister Nicky, who was spotted roaming the grounds yesterday, as well, although she seemed content going about the day apart from her attention-loving sister.
