We know that the cast members of The Hills have many outside talents: Lauren Conrad is an acclaimed young adult author, Heidi Montag makes a second living as a fitness instructor, and Audrina Patridge's blog reveals her to be a face cream connoisseur. But before last night, did we have any idea how skilled the Hills women are at cutting a rug? While watching the band White Tie Affair perform at the Roosevelt, Lauren & Co. kicked out the jams with a series of white-girl moves so fierce that they could be worked into common rotation for just about any type of song, no matter the genre. In fact, to test our theory, we tried out their moves to a very 90's backing track that just so happens to be making a Kanye-assisted comeback. Go Lauren, go Lauren, go! [MTV]
