The Oscars might have had surprise winners, but it's no surprise that everyone -- win or lose -- is still in the mood to party the night away at the huge after-parties.
Netflix scored the most Oscar noms for a studio this year with 20, and celebrated 2 victories at the San Vicente Bungalows in WeHo. Laura Dern, who won Best Supporting Actress for "Marriage Story," attended and was joined by a couple other Netflix movie big shots ... Martin Scorsese and Robert DeNiro. Marty came away empty-handed for directing "The Irishman."
Jennifer Aniston was also there, no nominations, but she's Jen ... and that's enough.
But, Jay-Z and Beyonce's after-party at the famed Chateau Marmont might take the prize for the most celebs -- like Kourtney Kardashian leaving little to the imagination with serious sideboob in her sparkly dress.
