Getting an early start on her Fourth of July celebration, Audrina Patridge was spotted at The Bank nightclub at the Bellagio Resort Hotel & Casino in Las Vegas last night (July 3).

The “Hills” hottie looked excited to be partying in Sin City, sporting a white cleavage-baring dress teamed with a pair of gold strappy high heels.

In related news, it sounds like Audrina’s new reality show, tentatively called “The Colony” is shaping up quite nicely, and according to a report she’ll begin filming next month.

An inside source told press, “The show is currently casting for Audrina’s new BFFs.  They have chosen a girl pursuing a music career. The others will also have some sort of artsy interest.  She (Audrina) wants to make sure they find people she actually wants to get to know.”
