She’s “Happier Than Ever.”

Billie Eilish is officially dating Nat Wolff — and has been for months, a source exclusively confirms to Us Weekly.

“Their friendship blossomed into a relationship,” the insider shares. “It’s going well. She’s smitten.”

Us Weekly has reached out to reps for Eilish and Wolff for comment.

Billie Eilish appears to be involved in a lovely new romance. The “Ocean Eyes” singer fueled romance rumors with former Nickelodeon star Nat Wolff in June 2025, when the pair was spotted sharing a kiss in Venice, Italy. Their outing came three months after Eilish and Wolff had fans questioning the nature of their relationship […]

Romance rumors have been swirling around the “Birds of a Feather” singer, 23, and the Paper Towns star, 30, since earlier this year, though they have yet to publicly respond to them.

However, Eilish and Wolff were recently spotted packing on the PDA, all but confirming they are an item. The couple passionately kissed while sipping champagne on a balcony in Venice, Italy, on Saturday, June 7, in photos obtained by Deuxmoi.

That same day, the Grammy winner, who came out as queer in November 2023, got cozy with the Naked Brothers Band alum on a water taxi in the city’s famed Grand Canal, as seen in pictures published by Page Six.

Written in the stars. Shawn Mendes and Camila Cabello, Kim Kardashian and Kanye West, and more celebrities went from just friends to something more over the years. In fact, some of the strongest relationships in Hollywood began on platonic terms. West and Kardashian did not start dating until 2012, but they first crossed paths nearly […]

Eilish and Wolff met in December 2023 at the Academy Museum Gala, where they bonded over their shared Tourette’s syndrome diagnoses.

“When I saw Billie on interviews, I said, ‘Oh, she’s one of us,’” Nat’s brother, Alex Wolff, who also has the neurological disorder that causes involuntary tics, told Variety in October 2024. “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.”

Nat appeared in Eilish’s “Chihiro” music video in June 2024 before his and Alex’s band opened for the chart-topper on select dates of her Hit Me Hard and Soft Tour from September to December.

Age is just a number. Billie Eilish and boyfriend Jesse Rutherford have taken their relationship public, despite criticism of their age difference. The “Happier Than Ever” singer, born in December 2001, first shared a photo of Rutherford (born in August 1991) on her Instagram after a Halloween outing in October 2022. The Neighborhood frontman dressed […]

The dating speculation did not start, however, until March when Eilish and the actor were spotted leaving the 2025 iHeartRadio Music Awards in Los Angeles together. Days later, an eyewitness told Page Six that the pair appeared “affectionate” while barhopping in New York City.

The “Bad Guy” singer previously dated The Neighbourhood frontman Jesse Rutherford from October 2022 to May 2023. They remain close friends.

“That’s my guy, truly one of my favorite people in the world,” she told Rolling Stone in May 2024 of the 33-year-old alternative rock star.

Nat, for his part, has been romantically linked to fellow Nickelodeon alum Miranda Cosgrove, his Palo Alto costar Margaret Qualley and Tell Me Lies star Grace Van Patten in the past.
