All tanned up from her recent island getaway, Audrina Patridge was on-hand as host of Fila's Fall 2009 Collection Launch Party in Las Vegas on Wednesday night (February 18).

Held at The Bank Nightclub at Bellagio, the "Hills" hottie playfully posed with one of the shoe brand's sneakers before greeting fans and signing a few autographs.

Continuing on their Hawaiian adventure, Audrina Patridge, Lauren Conrad and their “Hills” peeps were spotted chilling out on the beach on the island of Oahu.

Spending the day working and running errands, Lauren Conrad was spotted out filming a scene for "The Hills" at People's Revolution on Thursday (January 29).

After finishing up shooting, the MTV starlet hopped in her black Mercedes and drove over to the Wilshire House, where she handed her ride over to valet before running inside.
