You might not know it, but Nicole Scherzinger, the only recognizable or even semi-hot of the Pussycat Dolls, and Audrina Patridge of The Hills have a lot in common.

Nicole Scherzinger is currently dating Talan Torriero, who, like, went to his Laguna Beach prom with Kristin Cavallari, who was totally in, like, the rival clique of Lauren Conrad - who's now Audrina Patridge 's roommate! Woo!

They're also wearing the same dress below. Peep it.

Tell us: Who wore it better, Nicole Scherzinger or Audrina Patridge?
