Billie Eilish and Nat Wolff were seen kissing on a balcony in Venice, Italy, over the weekend after years of speculation about their connection.

According to E!News, the "BIRDS OF A FEATHER" artist was taking a photo of their champagne glasses when Wolff leaned in to kiss her against the banister. The Naked Brothers Band alum wore a plain grey t-shirt and Eilish a striped top. Her hair was down in natural waves as she smiled behind the camera.

The pair have been friends since 2023 and met through Wolfe's brother, Alex, who opened for a few of Eilish's HIT ME HARD AND SOFT tour dates. In 2024, Alex told Variety that he and his brother immediately bonded with Eilish over their shared experience with Tourette’s Syndrome.

"Billie and me and my brother, we all have Tourette's. And I think we all have bonded over that. Even when I saw Billie on interviews, I said, 'Oh, she’s one of us.' We know all the ways that we try to mute ourselves or try and chill ourselves out or soften ourselves for other people. And how nice it is to not have to do that for certain people."

The "Ocean Eyes" star is not only close to Alex and Nat but the entire Wolff family.

"Your family is literally the greatest thing that’s ever happened to me," Eilish told Alex during a 2024 interview with Vogue.

Eilish and Wolff have yet to publicly speak about their relationship as the Grammy-winning songstress promised that she would never talk about "who I’m dating ever again" after opening up about her sexuality last fall.
