It’s the biggest weekend for Hollywood … and the stars were out in full force Friday night to kick off the Oscars celebrations before the big show on Sunday.

The were multiple big bashes around town … including the CAA pre-Oscar party at the Living Room in Los Angeles and the YSL party, which was held at an undisclosed private residence.

Stars dropping by the CAA blowout were the likes of Jennifer Lopez, Kerry Washington, Eiza Gonzalez, Paris Jackson, Seth Rogen, Sebastian Stan, Chris Pine, Kevin Bacon, Khyra Sedgwick, Jesse Willaims, Anna Kendrick, Gayle King, Jon Hamm, Zoey Deutch, Joe Alwyn, Josh Gadd … and new couple Channing Tatum and Inka Williams.

Celebs rolling into the YSL party included Olivia Wilde, Adrien Brody and Zoë Kravitz …  some of whom also dropped by the CAA bash.

With The Oscars not far away, ya gotta imagine some of these celebs had gold on their minds while partying it up.

This year’s ceremony is gonna be a hot event — the somewhat controversial film “Emilia Pérez” is leading the nominations with 13 to its name, while movies like “Wicked” and “The Brutalist” trail behind with 10 noms each.

Mark Zuckerberg‘s wife Priscilla Chan celebrated the big 4-0 with a huge bash — but it was the META CEO who stole the show with his stunning onstage performance.

Zuckerberg uploaded an Instagram video capturing a portion of the fancy black-tie soiree with the couple’s friends — and he quickly became the center of attention.

Check out the footage Zuck posted Friday … Mark, in his black tuxedo, makes a grand entrance to a packed ballroom and rushes onstage.

Just like the pop rock star, Mark put on a wild performance, jumping on and off a piano and busting moves that made Priscilla — watching with the crowd — laugh her ass off.

You may recall … Boone wore a similar outfit while belting out his hit song, “Beautiful Things,” during the Grammys this year.

In the video’s caption, Zuck gave his wife a birthday shoutout and thanked Benson for creating a great tune. Benson even got in on the fun, reposting the vid on his own IG story with the caption “You’re wild for this.”

Could there be a Zuck-Boone collab in the future? We’ll just have to see.

A FedEx cargo plane was forced to make an emergency landing Saturday morning when part of the aircraft burst into flames mid-flight … and it was captured on dramatic video!

A spokeman for FedEx tells TMZ … Flight 3609 from Newark to Indianapolis experienced a bird strike during takeoff.

“Our crew declared an emergency and returned safely to Newark. We are thankful for the quick actions of our crew and first responders,” the spokesperson tells us.

Eyewitnesses told Fox News they heard a loud explosion around the time of the incident.

For the moment, there are no reported injuries and the plane appears to have landed safely.

Air traffic was briefly halted as a precaution at the airport, but operations have since resumed, according to online tracking data.
