So now, of course, it's time see just what happened once all the awards were handed out, and Hollywood's finest headed off to let their hair down.
What we've learnt from these candid Instagrams? Brie Larson is a girl after our own heart (hello post-midnight Converse), Rebel Wilson is also open to stalking Leonardo DiCaprio when the oportunity arises, and Elton John sure knows how to throw a party.
From the Governors Ball and Vanity Fair after-party, to Elton John's legendary viewing bash, here's all the backstage action from the biggest night in Hollywood...
