The dancing never stops! Dancing with the Stars contestant Audrina Patridge
had a mini-Hills
reunion with pal Whitney Port
at Las Palmas in L.A. Patridge was there to host a launch party for Ubisoft's Just Dance 2
, a new Nintendo Wii video game. At one point, she teamed up with Port for a spirited run through the game, busting a move on the dance floor. But they also spent time gossiping and catching up at the bash, which also brought out DWTS
pro Karina Smirnoff

co-host's L.A. home. The group also celebrated with cake batter-flavored Cold Stone Creamery ice cream – and some signature cupcakes.
