Katy Perry got a mini-sized taste of herself last night at Mr. West nightclub. The singer celebrated the premiere of her new music video, "Waking Up in Vegas," with PEOPLE Magazine and a SVEDKA Vodka cocktail party. Best friend Rihanna dropped by the party, as well as on again/off again and definitely back on again boyfriend, Travis McCoy. This is the second night in a row Rihanna and Perry hit the town together.

The house DJ took requests from Perry and Rihanna, and when Rihanna's hit single "Umbrella" came on, Perry made the popstar stand-up on the banquette and dance with her. A miniature Perry-look-a-like crashed the event and Perry was thrilled, taking photos with the impersonator and dragging her onto the dance floor. Rihanna, Travis and Perry hung at their VIP table dawning a bottle of SVEDKA Vodka and stayed until the wee hours of the morning.
