All you male Gleeks—take a deep breath before you look at this photo. Dianna Agron is just a little too hot to handle right now. At last night's premiere for I Am Number Four, the former Cheerio worked it on the carpet with a very bare, very nude Vivienne Westwood draped dress paired with hot red satin Brian Atwood pumps. We're all very used to seeing this blond bombshell in a cheer uniform and mischievous smile, so it's a pleasant surprise to see Agron step out of her uniform and into a very sophisticated ensemble. With effortless, up-swept hair and simple accessories, Agron is now officially on our style radar. (CocoPerez)
