Kaia Gerber and Austin Butler Dress as Edie Sedgwick and Andy Warhol for Casamigos Halloween Party

The couple attended the annual Casamigos Halloween bash dressed as the two '60s icons of art and fashion

Kaia Gerber and Austin Butler transformed into stars of the '60s for Halloween this year!

On Friday night, the actor, 32, and model 22, showed off their very chic Andy Warhol and Edie Sedgwick costumes at the annual Casamigos Halloween Party in Beverly Hills — hosted by Kaia's parents, Rande Gerbe and Cindy Crawford.

Both Kaia and Butler embraced the Halloween spirit fully for the event, sporting short wigs for their respective costumes as well as detailed outfits reflecting the two art and fashion icons from the '60s.

It appeared the pair's costumes were inspired in part by looks worn by Sedgwick and Warhol at the 1965 New York Film Festival, and they looked every inch as glamorous as the '60s icons did almost 70 years ago.

Along with his blond Warhol wig, Butler teamed sunglasses with a black turtleneck sweater, black leather jacket and black pants. Meanwhile, Kaia sported a sleeveless black turtleneck and opted for a pants-less look of just black tights and black Mary-Jane heels. She was also spotted with what appeared to be a faux-fur jacket on during the Halloween bash, and, of course, had added Sedgwick's signature chandelier earrings to her costume.

Along with Kaia's famous family, the couple was joined at the event — which featured a fantastical garden and Wonderland in the backyard — by celebrities including Paris Hilton, Justin Bieber,   Sarah Hyland and Wells Adams, Jason and Brett Oppenheim, Alessandra Ambrosio, Glen Powell, Jenna Dewan, Victoria Justice, Edward Norton, Megan Fox and Machine Gun Kelly.

Ahead of the annual bash, the duo was recently seen together at Paris Fashion Week, where Butler supported Gerber’s many runway appearances. The daughter of supermodel Cindy Crawford and Casamigos Tequila co-owner Rande Gerber walked Alexander McQueen’s final show for creative director Sarah Burton.

In a lengthy post dedicated to Burton, Gerber wrote, “In your 26 years at McQueen, you carried the torch with the utmost grace, attentiveness, and creativity. You dreamt for all of us and brought those dreams to life."

It continued: "Your designs felt like a gentle armor, like a thoughtful articulation, like a warm hug. Like they were made for us. And dear maestro, they were.”

Throughout the week, Gerber and the Elvis actor were spotted several times walking the streets of the French capital hand-in-hand, and Butler often sat front row at his model girlfriend’s shows.

The pair first took their relationship public at W magazine's annual Best Performances party in March 2022, months after being spotted spending time with one another following Gerber’s split from Jacob Elordi.

"She seems really happy," an insider previously told PEOPLE of Gerber's relationship with Butler. "All of her friends think he's really cute."
