The Met Gala: Beyoncé's dramatic arrival and Bruno Mars's performance

The Met Gala took place Monday night in New York to launch the opening of The Metropolitan Museum's new exhibition Schiaparelli and Prada: Impossible Conversations. Bruno Mars's performance and Beyoncé's entrance were among highlights noted on Twitter.

Marc Jacobs showed up in a lace dress, Coco Rocha came in a vintage Givenchy pantsuit that once belonged to Elizabeth Taylor and Lana Del Rey, sporting her well-practised pout, was told by E!Online to "cheer up." But Beyoncé got the most tweets for her showstopping arrival in a Givenchy gown. Bruno Mars's performance was called everything from "way fun" by Rachel Zoe to "ethereal and electric" by Desiree Gruber.
