Once the Oscars ceremony is over, there's only one place to be - the Vanity Fair after-party hosted by the magazine's editor Graydon Carter.
This year, the winners, nominees and presenters were all invited to let the hair down and celebrate the end of awards season in style at a custom-built venue in Beverly Hills.
We can only imagine the kind of shenanigans Hollywood's royalty get up to once the official proceedings are over. Thankfully, photographer Mark Seliger was on hand to capture the mood post-Oscars "during an impromptu late-night photo session" with a few of the famous party guests.
Best Actor and Best Supporting Actor winners Eddie Redmayne and J.K. Simmons were just two of the stars who posed for these stunning Instagram portraits.
Other A-listers included a stunning shot of Jennifer Aniston and Justin Theroux, Lady Gaga, Rita Ora and "smiling swans" Natalie Portman with Rashida Jones.
