Bruno Mars kills it at the Met Ball gala

It was a night of the stars at the annual Costume Institute Gala Met Ball in NYC tonight — also known as the fashion world’s Oscars. But fashionistas took a backseat to pop icon Bruno Mars, who brought down the house with a surprise performance that included covers of “Roxanne” by The Police and “Dirty Diana” by Michael Jackson. Among the smitten starlets? Rachel Zoe, Sofia Vergara, Kate Bosworth, Karen Elson, and Mars’s not-so-secret crush, Rosario Dawson.

Diehard fans — “Hooligans” — enjoyed the Twitter love for Bruno. And his hair:
