Hollywood's A-list crowd hit up the magazine's annual post-Oscars get-together -- which has become a staple during awards season, and where just about everyone who was in town swung by to have their photos taken and to hobnob with other celebs post-show.

Of course, ya can't blame anyone for wanting to hit up this Oscars bash -- the red carpet and giant lettering is eye-catching, to say the least, and everyone's dressed to the nines.

The pap shots were something to behold, but once people were inside and mingling -- there was a lot to see there as well ... with lots of different stars crossing paths and exchanging smiles. Indeed, Oscar winners themselves were on hand ... as were the runner-ups.

Some of the celebs on hand ... Da'Vine Joy Randolph, Emily Blunt and John Krasinski, Margot Robbie, America Ferrera, Billie Eilish, Jeff Bezos and Lauren Sanchez, Sydney Sweeney, Sofía Vergara, Lenny Kravitz and lots of others.

FWIW, that wasn't the only game in town ... Beyoncé and Jay-Z threw another party at the Chateau Marmont -- and that bash was just as star-studded. In fact, there may have been some double dipping here.

Just a smidge of the stars who showed up for Jay and Bey's party -- the KarJenners, LeBron James, Kelly Rowland, Ciara and Russell Wilson, Chrissy Teigen and John Legend, Emma Stone, Mark Ruffalo, MGK and Megan Fox, Kerry Washington and more.

It was certainly a night to remember ... especially for some movies like "Oppenheimer," "Poor Things," "The Zone of Interest" and a handful of other flicks that truly cleaned up and swept.

"Barbie" left relatively empty-handed ... as did "Killers of the Flower Moon." That's not to say people weren't happy at the actual ceremony, though ... 'cause they absolutely were.

Peep all the photos showing the behind-the-scenes. A night to remember and then some!
