The Style Crowd Makes This the Most Fashionable Night at the Museum

Full disclosure — there are some red carpet events that seem a little less thrilling than others. But then there are the parties we'd die to be at — whether it's for the killer fashion choices, the talked-up performances, or the fun mix of stars in attendance. Last night's American Museum of Natural History Gala definitely falls into the latter category.

Not only was Tina Fey the host of the evening's annual benefit, which supports the museum's programs in education and science, but Bruno Mars performed and dinner was served up by none other than Mario Batali. And fashion's elite and funny faces alike stepped out to celebrate. So, of course, you can only expect that the glamorous dresses were not to be glossed over.

Dianna Agron channeled her inner boho princess while Cameron Diaz worked an eye-catching Chalayan design, and Naomi Campbell slipped on a Tom Ford mosaic-tile number you have to see in full. But they weren't the only stars we were happy to find mingling. Get an inside look at the party ahead — you won't believe who showed up.
