Who Is Billie Eilish Dating? All About Her Rumored Boyfriend, Musician Nat Wolff

Could Billie Eilish have someone new in her life? Fans are convinced the answer is yes after the Hit Me Hard and Soft singer was spotted having a steamy make out session with actor and singer-songwriter Nat Wolff, People reported.

It’s not the first time romance rumors have swirled around the two artists. In March 2025, the pair were photographed leaving the iHeartRadio Music Awards together. The following week, Page Six reported that the pair attended a play and went bar hopping together.

The musicians, who both rose to fame at young ages, previously collaborated on Eilish’s song “Chihiro.” Wolff, 30, starred in the music video for the pining anthem, which the 23-year-old artist directed. In the music video’s press release, she said it represents their “inescapable connection,” per People. Later, Eilish produced and sang on the track for Nat & Alex Wolff’s song “Soft Kissing Hour,” which the pop-rock duo announced while opening on her tour.

“Your family is literally the greatest thing that’s ever happened to me,” Eilish told Wolff’s brother Alex during a joint June 2024 Vogue interview. Although neither Eilish nor Wolff have confirmed the rumors of their romance, the pair have publicly shared that they’re good friends. Here’s everything to know about Nat Wolff.

Wolff was one-half of The Naked Brothers Band.

Millennial and Gen Z fans of Nickelodeon know Nat and Alex Wolff from The Naked Brothers Band, a mockumentary-style TV show that followed the so-called child rockstars. The band wasn’t fictional—Nat and Alex really wrote, recorded, and performed Naked Brothers Band songs on-screen and around the U.S.

Of course, rising to fame as a child—Nat was 12 when the show premiered—meant he spent the turbulence of adolescence in the spotlight. “[At] about 14, I grew really tall and started looking different and nobody knew who I was all of a sudden,” he shared with American Studies in 2024. 

Speaking of the “formative experience” of gaining and losing fame before starting high school, he further explained, “It made me double down and refocus on the original reason behind why I started doing these things—my love of music and acting and my need to be creative.”

The Naked Brothers Band ran for three seasons, and while the band might not be together anymore, the titular brothers now make more music as the duo Nat & Alex Wolff.

He’s from a creative family.

Creativity runs in the DNA of the Wolff brothers. Their mother, Polly Draper, is an actress, writer, and producer—she helmed the original mockumentary that got her sons their own spin-off TV show, The New York Times reported. Their father, Michael Wolff, is a jazz pianist and former bandleader on The Arsenio Hall Show.

As for growing up in the city that never sleeps, Nat has expressed appreciation for his childhood in the city. “I think that [being from NYC is] really great because we grew up around a million different types of people when we were very, very young. And so that was probably good for our influences musically and just in our lives,” he told V Magazine in a 2021 interview.

While their own careers have taken off, the brothers still find time to catch up with their close-knit family. They even invited their father onstage when they opened for Eilish at Madison Square Garden in October 2024, the older Wolff shared during the WBGO/Yamaha Concert Series. Nat and Alex performed “Shake,” a song Nat wrote about their father’s battle with cancer. Michael Wolff is now in remission—and he’s met his son’s rumored girlfriend.

“[Eilish]’s really a wonderful artist, you know. I’ve gotten to know her. She’s a great person,” the patriarch said at the aforementioned concert series.

He starred in ‘The Fault In Our Stars’ and ‘Paper Towns.’

Following his childhood role in the aforementioned Nickelodeon show, Nat also starred in not one but two adaptations of John Green’s beloved YA novels. First, he was comedic relief character Isaac in 2014’s The Fault In Our Stars before his starring turn in 2015’s Paper Towns alongside model-turned-actress Cara Delevingne.

Stepping into the role of a typical high school teen offered him a chance to experience the normal childhood he didn’t quite have. In a Variety interview, he explained that it “felt like I almost went in a time machine back to a time where I was a little more innocent and I had two best friends. […] And by the end of the movie I just wanted to live in that world. I didn’t want to leave.”

Nat took the newfound wave of attention from Green’s dedicated fanbase in stride. “It would cause me too much anxiety to assess my career and [for] that [fame] to be a factor. It can’t be a factor,” he told WWD ahead of the Paper Towns premiere. “I just need to work on things that I’m proud of and be nice to people who come and see them.”

Like Eilish, he has been open about having Tourette’s syndrome.

From her earliest days in the public eye, Eilish has been candid about every part of her personal life—including her diagnosis with Tourette’s syndrome, a neurological disorder characterized by involuntary tics. Eilish received the diagnosis when she was 11 years old, and opened up about living with the condition in a 2022 interview with David Letterman.

“If you film me for long enough, you’re gonna see lots of tics,” she said on the veteran host’s Netflix series, My Next Guest Needs No Introduction. The singer noted that when she’s performing, she’s “not even ticcing at all.”

Her rumored beau also has Tourette’s syndrome, as does his brother Alex. “I think we all have bonded over that,” Alex told Variety in a 2024 profile. “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 two met at an Oscars after party.

Variety reported that Alex and his brother first met Eilish at a 2024 Oscars party. Alex had a part in Christopher Nolan’s season-sweeping biopic Oppenheimer, while the “What Was I Made For?” artist nabbed that year’s Academy Award for Best Original Song thanks to her emotional Barbie contribution.

After the Oscars meetup, they attended Coachella together. The brothers’ joint Instagram carousel post about their festival memories includes several snaps of the singer and Nat, alongside several group photos with their friends.

Paparazzi shots from their June 2025 Venice vacation have fans convinced they’re now an item. Besides steamy shots of their balcony makeout, they were also spotted taking a romantic boat ride down the Grand Canal in photos published by Page Six.
