Sydney Sweeney, Hailey Bieber, Seth Rogan & More Hit GQ Men of the Year Party

Sydney Sweeney, Hailey Bieber, Seth Rogan, and a whole lot more celebs brought the ’90s back in a big way Thursday night … hitting the red carpet dressed to the nines for the GQ Men of the Year 2025 Party.

The event went down at the Chateau Marmont in Los Angeles … and to celebrate three decades of the iconic issue, GQ leaned all the way into a throwback theme, “Party Like It’s 1995.”

Sydney Sweeney looks radiant in a vintage Versace black dress, complete with a choker and dramatic eyeliner … while Hailey Bieber stuns in a sparkling, see-through black Gucci gown.

Stephen Colbert is looking sharp alongside his wife, Evelyn — rocking a leather jacket, crisp striped shirt, polka-dot tie, and aviators. Seth Rogan, meanwhile, is all business on top, party on the bottom … pairing a button-down shirt, blazer and tie, complemented with a baggy blue jeans.

Oscar Isaac is too hot to handle … stepping out in a dark pinstriped Tom Ford suit, accessorized with an Audemars Piguet watch, loafers, and a fresh pair of shades.

Check out the gallery … Regé-Jean Page, Chase Sui Wonders, Alix Earle, Aziz Ansari, Walton Goggins, Patrick Schwarzenegger, Dixie D’Amelio, Coco Jones, and Shay Mitchell came in their best looks.
