Star of the music world – and uhh, Larry David – were out in force for the NYC event.
Last night was New York's annual Met Gala: a swanky event for A-list celebrities held at the Metropolitan Museum Of Art, in order to raise funds for the museum's costume institute. No surprise to see music's President and First Lady, ie Jay Z and Beyonce, in attendance, then.
Lots of other musicians were at the event, too, showing off their fancy-dan clothes and pouting for the paps. Rapper P Diddy was one of the guests, accompanied by Miley Cyrus.
Cyrus was also spotted with The Voice judge/mentor/chair-spinner Rita Ora, too.
But they all looked a bit dour compared to Rihanna, didn't they?
Kanye West, meanwhile, took time out from working on his new album to head to the Met Gala with wife Kim Kardashian. The rapper's also recently been working on a clothing line for sports brand Adidas.
Of course, if you really want to turn heads, a swish outfit isn't enough - you need a personal lackey to kiss your hand, too. Hats off to Katy Perry.
FKA Twigs was at the Gala, too, along with her actor boyfriend Robert Pattinson.
No, we're not sure what Justin Bieber was thinking either.
Whereas Solange was seemingly going for the sci-fi inspired 'portal to another galaxy' look.
And finally, beware, Drake: here's Madonna descending upon the Met Gala. Although the Queen of Pop didn't have any cape mishaps this time, thankfully.
