Nicole Scherzinger and Paris Hilton are gaga for Lady Gaga! The celebs got gussied up last night for Mother Monster's Los Angeles show at the Staples Center.

For the night on the town, Nicole donned a super sexy midriff-baring black ensemble, paired with some sporty kicks. While Paris went for a demure but funky dress with striped tights. In the style wars, we have to say -- we think NIcole wins hands down.

While at the concert, Paris got to meet her drag queen counterpart and it looks like she got quite the kick out of it! Seems like an eventful night for the on-the-go socialite.

During the concert, Gaga treated fans to Venus," Paparazzi," G.U.Y. and a plethora of other hits. We're sad we missed out!
