Austin Butler and Zoë Kravitz’s chemistry is sizzling off-screen, too.

The “Caught Stealing” co-stars sparked even more romance rumors at their film’s premiere in Paris on Thursday. They paused on the red carpet to lock eyes while being photographed, fueling speculation about their relationship.

Kravitz, 36, and Butler, 34, smiled as they shared a moment, looking completely at ease with one another.

The “Blink Twice” director exuded style in a champagne-hued lace slip dress, accessorized with an arm bracelet, dangling earrings, and sleek black sandals.

Butler showcased his fashion sense at the premiere, donning leather pants along with tan and black layered button-up shirts. His outfit was polished off with a straightforward silver watch.

Kravitz and Butler have been making headlines for their red carpet interactions. On Tuesday, the Oscar-nominated actor rescued Kravitz from an aggressive bee at the “Caught Stealing” premiere in London.

Butler plays Hank in the film, a baseball star turned bartender who finds himself immersed in the criminal world of 1990s New York City. Kravitz plays Yvonne, his love interest.

Last month, Page Six exclusively reported that the two attended an immersive theater show in NYC together, further fueling speculation the two are dating.

But a source told Page Six in April that Kravitz and Butler‘s flirtation was “nothing serious” after she ended her engagement to Channing Tatum in October 2024.

“With Austin, it’s an opportunity to have fun, keep her mind off things right now,” the source said. “I’m sure she’s not the happiest with what happened [with Tatum]; it’s a good way for her to have fun and hang out. Who wouldn’t be interested in Zoe?”

“She is gaining the clout that can definitely help someone’s career. He’s [Butler] the ‘it’ guy in Hollywood, she’s the ‘it’ girl. I’m sure he’s not opposed to the attention,” the source continued. 

Butler was last linked to Kaia Gerber, whom he dated for three years before they split in late 2024.
