There was a bit of confusion in the Zap2it offices when we saw a gorgeous woman with smoky eyes and wearing a black dress hit the red carpet.

Who's that girl? To our surprise, it's Dianna Agron, 24, who's sending some edgy rock and roll vibes with the edgy hair, cat eyes, and black dress combo.

Agron not only looked very different from her character, teenaged Quinn on FOX's "Glee," but she looked quite the woman - a smokin' hot woman at that.

Agron and her castmates were nominated for Best Pop Performance by a Duo or Group for their version of Journey's "Don't Stop Believin." Train ended up taking the award for "Hey, Soul Sister."

Did Dianna's look surprise you, too?
