Robert Brown|Austin Butler and Kaia Gerber Seal Their Romance With a Kiss During Movie Premiere

Austin Butler and Robert BrownKaia Gerber showed off their burning love on the red carpet. 

In fact, the Elvis star and model—whose romance was made public in 2022—were spotted sharing a sweet kiss during the premiere of his new movie The Bikeriders, which hits theaters June 21. 

In a clip from the June 18 event in Los Angeles, Austin, 32, was seen making his way through the crowd to Kaia, 22, who sported long pin-straight hair and was clad in a short black dress. The Bottoms actress greeted him with an excited smile before he leaned over for a kiss on the lips. 

And while the smooch marks a rare moment of PDA for Austin and Kaia, they're certainly no strangers to attending events as a couple. After all, they made their red carpet debut at the 2022 Met Gala, where Kaia stunned in a floor-length Alexander McQueen gown and Austin rocked an all-black Prada suit. Since then, they've also turned a handful of other major public outings into date nights, including Vanity Fair's 2023 Oscars after-party and the 2023 TIME100 Gala. 

Still, there are parts of their relationship that will always remain between them. As Kaia put it to WSJ. Magazine back in February, "Honestly, I feel like so few things in my life are private, and that is one of the things that I try to keep as sacred as possible."

For the daughter of Cindy Crawford and Randy Gerber, maintaining that sense of privacy is key to building a healthy foundation for a relationship. 

"You have to silence the outside world," she told i-D in 2020. "The only people who know anything about anything are the people in the relationship. The public is very loud, so you have to make your own feelings even louder."
