Billie Eilish and Nat Wolff Make Their Red Carpet Debut

Billie Eilish has officially hard-launched her relationship — and she did it in style. The Grammy-winning singer and her boyfriend, actor Nat Wolff, stepped out together on the red carpet Wednesday night at the Los Angeles premiere of her new concert film, Billie Eilish — Hit Me Hard and Soft: The Tour (Live in 3D), making it their first official public appearance as a couple.

The two smiled, hugged, side-hugged, front-hugged, and leaned into each other for the cameras at the Fox Westwood Village Theater — the kind of easy, comfortable body language that tells you everything you need to know. At one point, Wolff rested his cheek on top of Eilish’s head while she beamed at the cameras. A second shot showed them embracing and laughing, looking completely at ease.

Eilish, 24, wore an oversized emerald green Ralph Lauren polo layered over a white long-sleeve button-down, paired with a black pleated skirt, red crew socks trimmed in navy, and cream kitten-heeled pumps with ombré toes and sneaker-style laces. It’s the kind of look that shouldn’t work — prep, punk, and jock all at once — but absolutely does. Wolff, 31, kept it classic in a brown double-breasted suit over a white shirt, no tie.

They were joined on the carpet by Eilish’s brother and longtime collaborator Finneas O’Connell and his girlfriend Claudia Sulewski, her parents Maggie Baird and Patrick O’Connell, and the film’s co-director, James Cameron. The Avatar: Fire and Ash filmmaker co-directed the concert movie with Eilish, which chronicles her sold-out four-night run in Manchester, England last year and hits theaters on Friday.

Who Is Nat Wolff?

If you’re not already familiar with Wolff, here’s the quick version: he’s a 31-year-old Los Angeles-based actor and musician who got his start alongside his younger brother Alex on Nickelodeon’s The Naked Brothers Band, a mockumentary series about their lives as kids in a band. He went on to build a solid film career, landing roles in The Fault in Our Stars, Paper Towns, Stuck in Love, and Death Note.

He and Alex still make music together as Nat & Alex Wolff. And as of late 2024, that band had a pretty high-profile gig: opening for Billie Eilish on the US leg of her Hit Me Hard and Soft tour.

Alex Wolff, for his part, is probably best known to horror fans for his role in Hereditary. The brothers are a package deal in the best possible way.

How Billie and Nat Actually Got Together

The story of this relationship starts, as many good ones do, with a shared experience that cuts deeper than small talk. Eilish, Nat, and Alex all have Tourette syndrome — and that’s what first bonded them.

Alex met Eilish at an Oscars party in March 2023. “Billie and me and my brother, we all have Tourette’s. And I think we all have bonded over that,” Alex told Variety. “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.”

Nat met Eilish separately at the Academy Museum Gala in Los Angeles, where they also connected over their Tourette’s. By April 2024, the three of them were at Coachella together, documenting it on Instagram. That June, Nat starred in the music video for Eilish’s song “Chihiro” — a self-directed clip she described as representing the characters’ “inescapable connection.” Following its release, Wolff posted on Instagram calling Eilish “my (favorite) artist and (favorite) human” and praising her as “not only a genius singer and songwriter but also an amazing director and editor.” Eilish responded in kind: “One of my favorite videos I’ve made and truly one of the greatest days of my life. Nat, love you so much. Thank you for being a part of this.”

In a 2024 Vogue cover interview, Eilish called Nat and Alex “some of my best friends in the world.” Nat, in the same piece, was characteristically effusive about her: “She’s one of those people where almost everything she does, she does better than everyone else. She’s like, ‘Come see me ride my horse,’ and the teacher says, ‘You know, if she put all her energy into it, she could go to the Olympics.’ You just have to kind of submit to the fact that she’s going to be better than everyone else at everything.”

Romance rumors started swirling in March 2025, when Eilish and Wolff were spotted leaving the iHeartRadio Music Awards together, then bar-hopping across New York. Sources told Page Six at the time that they were “very affectionate.” Other sources pushed back, insisting they were just close friends. Then came June 2025.

DeuxMoi dropped photos on June 8 of the pair kissing on a private balcony in Venice — sipping Champagne, smooching, cuddling on a gondola ride through the canals. Wolff was photographed grabbing Eilish by the cheeks and kissing her, and snapping photos of her with a digital camera. The internet, predictably, lost its mind. An insider confirmed to Us Weekly shortly after: “Their friendship blossomed into a relationship. It’s going well. She’s smitten.”

The months that followed were quiet — no major sightings, no official statements, which is very much in keeping with Eilish’s stated approach to her private life. In her 2024 Vogue interview, she had been clear: “I’m never talking about who I’m dating ever again.” She’s spoken openly about regretting how much her previous relationships played out in public. “I guess I underestimate that things I say will be blown up into the biggest news of the whole world. That’s so unnatural. We’re all babies. We’re all little kids growing up and learning ourselves,” she said.

Then, in February 2026, the couple turned the Grammy Awards into a date night, photographed cozied up together at their table. Eilish also publicly supported the Nat & Alex Wolff self-titled album on her Instagram Stories. And then came Wednesday’s premiere — the full hard launch, red carpet and all.

In a 2026 interview with Interview magazine, the brothers reflected on what they took from the experience of touring with Eilish, saying they learned “how to be a world class artist with grace” and how to make fans “feel so special and beloved.”

The concert film that brought them all to the carpet together, Hit Me Hard and Soft: The Tour (Live in 3D), is Eilish’s third concert movie and her first since Happier Than Ever: A Love Letter to Los Angeles in 2021. It opens in theaters Friday. And up next for Eilish: she’s reportedly set to make her acting debut in The Bell Jar, Sarah Polley’s adaptation of Sylvia Plath’s 1963 novel, where she’ll play lead character Esther Greenwood.

But for now, she’s got a boyfriend on her arm and a movie opening this weekend. Not a bad week.
