While not everyone gets an invite to the ceremony (and of those who do, not everyone wants to go), but the stars really turn out for the biggest event of the Oscars - the after party!
The Vanity Fair party seemed to be where it was at last night after the 88th Academy Awards.
Burgers were eaten, champagne flowed, and celebs made small talk with each other.
Here's the greatest pairings of the night:
Taylor Swift and her BFFs
Taylor of course hung out with her besties Lorde, Selena Gomez and her brother.
They were even snapped being super glamorous by the Vanity Fair photographer.
Elizabeth Banks, Kate Upton and Maria Sharapova
Do blondes really have more fun? You might have to ask these three - who certainly seem to be having a hoot.
Jessica Biel and Demi Lovato
This seems like a surprising pairing, but the fact they are clutching their shoes after what looked like a bit of wild partying makes me love them even more.
Brie Larson and a Cheeseburger
She may have taken home an Oscar, but she did not leave the Oscars after party with a hamburger which she devoured with glee, and posted the moment on Instagram. She sure knows how to have a good time.
Jacob Tremblay, Sofia Vergara and Daisy Ridley
Meanwhile, Brie's Room co-star, Jacob Tremblay, buddied up with none other than Sofia Vergara. He was later snapped at the after party with his Star Wars idol, Daisy Ridley.
Anne Hathaway and Eddie Redmayne
It's a Les Miserables reunion! (With a heavily pregnant Fantine!)
Lady Gaga and Caitlyn Jenner
These two are like peaches and cream! We're not sure what they were whispering about, but we imagine it's something along the lines of: "You look amazing!" "No, you look amazing!"
The "D**k in a Box" crew
Remember that band, The Lonely Island? Remember that time they recruited Justin Timberlake to sing a song with them about penises in boxes? Well, that happened, and seven years later they hung out at the Oscars after party.
Jake Gyllenhaal and Bono's daughter
Yep, that's the U2 frontman's grown up daughter, Eve Hewson. Is it just us, or does it look like they're flirting up a storm?
Jennifer Garner and Melissa George
Only days after Jen's explosive Vanity Fair cover story about her relationship with Ben Affleck, she attended the Oscar's after party (where he also was) and had a good ol' laugh with Melissa George.
Leonardo DiCaprio and Everyone
Everyone wanted a piece of this Oscar-winning hunk. He was spotted chatting to everyone from Chris Rock, to Elton John, to Ben Affleck, to Rebel Wilson.
