Austin Butler and Kaia Gerber channel an iconic '60s duo for a couple's costume

There's a new Hollywood couple in the spotlight: Austin Butler and model Kaia Gerber.

The "Elvis" actor was first spotted in December 2021 taking a yoga class with the model, who is the daughter of Cindy Crawford, sparking rumors the two could be dating.

Butler, 32, and Gerber, 22, have made quite a few public appearances since going public with their relationship (PDA included.) At the 2022 Met Gala, the two shared a kiss at the top of the Metropolitan Museum of Art staircase.

Now, the pair seems to be taking their relationship to the next level: a couple's costume.

Gerber and Butler attended the annual Casamigos Halloween party as model Edie Sedgwick and pop artist Andy Warhol, respectively. Each wore a spiky wig and all black, indicative of the 1960s style.

Sedgwick was notably one of Warhol's superstars, and the two are remembered for having a passionate and tumultuous yet brief affair.

The event was co-hosted by Gerber’s parents, Cindy Crawford and Rande Gerber.

Butler previously dated Vanessa Hudgens for nine years. Their relationship ended in January 2020, around the time that Butler began his role for "Elvis." He credits part of his success in the role to Hudgens.

“We’d been together for so long and she had this sort of clairvoyant moment and so I really, I owe her a lot for believing in me,” Butler told the Los Angeles Times.

Gerber was previously linked to "Euphoria" star Jacob Elordi, 26. The two called off their relationship a month before Gerber was spotted with Butler.

Butler and Gerber have kept details of their relationship out of the public eye, but have showed up on red carpets. Keep reading for a timeline of what we know about their relationship.

May 2021: Gerber opens up about her relationship pattern

A few months before Butler and Gerber were first spotted together, Gerber spoke about how her lack of a typical high school experience lead to her tendency to date people older than her. Butler is 10 years older than Gerber.

“I was doing Fashion Month, but I was so young I had kissed, like, only one person. I had never had a high school sweetheart or anything,” Gerber, who was 19 at the time, told Elle Australia. “And so I tended to date older people because those were the people I was around. And I got put in situations where one day I’d wake up and be like, How did I get here? I have no idea what I’m doing, and I need help. And being able to ask for that help was amazing. That’s what real growing up means, not being afraid to ask.”
