Leighton Vamps It Up At Butter

Last night Robin Thicke held his album release party at NYC hotspot Butter, and everyone from Leighton Meester to Jay-Z and Beyonce showed up to celebrate.

After performing a few tunes, Robin called the Gossip Girl star up onstage, and the two performed their new single, "Somebody To Love." Leighton looked gorgeous as always, but it appears as though she's begun to adopt a much edgier style. Perhaps to go with her transition from actress to pop star?
