Who Is Stacy Martin Dating Now? The Truth About Her Ex-Boyfriend Daniel Blumberg

Stacy Martin is a French-British actress who broke through with a fearless performance in Lars von Trier’s provocative epic Nymphomaniac.

Since then, she has built an impressive career working with directors like Brady Corbet (The Brutalist, Vox Lux) and appearing in acclaimed films such as All the Money in the World and the BBC series The Serpent.

Yet for years, one of the most consistent presences in her life has been musician and composer Daniel Blumberg. Their love story, spanning over a decade, has been marked by a breakup, a heartbreak album, a reconciliation, and eventually an amicable separation.

Here is everything you need to know about Stacy Martin’s relationship with her now-former boyfriend Daniel Blumberg, the timeline of their breakup, and where they stand today.

Who is Daniel Blumberg? The Oscar-winning musician

Daniel Blumberg is a British musician, composer, and visual artist from London. He first gained attention as the frontman of the indie bands Cajun Dance Party and Yuck in the late 2000s and early 2010s.

However, after growing disillusioned with the commercial music industry, he walked away from mainstream success to pursue experimental, improvisational music. He has since reinvented himself as a celebrated film composer.

Blumberg has worked on scores for The World to Come (2020) and the Oscar-winning The Brutalist (2024), for which he won the Academy Award for Best Original Score. He also scored Mona Fastvold’s The Testament of Ann Lee and has collaborated closely with director Brady Corbet on multiple projects.

In addition to his musical work, Blumberg is a prolific visual artist, described by curator Hans-Ulrich Obrist as “one of London’s most exciting emerging artists”.

The seven-year relationship and devastating split

Stacy Martin and Daniel Blumberg began dating when Martin was just 19 years of age. According to Blumberg, they met at a time when both were struggling with mental health issues and found a unique understanding in one another.

In a 2018 interview, he referred to Martin as his “partner since the age of 19, with whom he experienced the breakup.” So, they officially began dating around 2011, and for seven years, they were inseparable.

The couple’s relationship came to a sudden and painful end in early 2018. According to Blumberg, the breakup was “bad” and left him devastated. The split occurred just as Blumberg was preparing to record his debut solo album.

He was also struggling with his mental health, and the combination of heartbreak and depression led him to be hospitalized just a week before entering the studio. “Things were collapsing around me,” Blumberg recalled.

“I became entirely monomaniacal about the record. It was as if everything came to depend on its completion,” he concluded his statement.

The ‘Minus’ album: Music born from heartbreak

Blumberg channeled his grief into his music. The result was Minus, an album recorded live over five days in Wales. The record is a raw, deeply personal exploration of heartbreak, loss, and recovery.

In an interview, Blumberg revealed that he wrote much of the album while isolated with a broken heart. He credited a friend sending him a song record as the spark that reconnected him to songwriting.

The album was recorded with a group of radical musicians whom Blumberg met at London’s Café OTO, including violinist Billy Steiger, double bassist Tom Wheatley, cellist Ute Kanngiesser, and saxophonist Seymour Wright.

Minus is an album about breakdowns: relationship breakdowns, mental and physical breakdowns, breakdowns in communication, and the breaking down of received methods and practices.

The lyrics are sparse but devastating, with Blumberg singing lines like “I zip up my mind like I zip up my jacket” on the track ‘Used to Be Older.’ One of the most poignant tracks to emerge from the Minus sessions was “Family.”

The standalone single was recorded in one take. Blumberg explained that the song felt “like the album all rolled into one” and that he decided to release it separately because it was “too much to be on the record and needed to come out on its own with its own space.”

The music video for “Family” was shot by Blumberg himself and features Stacy Martin in a Parisian hotel room. The video is a highly intimate portrait, with the camera slowly scanning a hotel hallway before settling on a close-up of Martin’s face.

For Blumberg, the video was a way to process the end of their relationship. “There was a time when it meant everything to me,” he said. “I was finding life too difficult, so I thought I’d just focus on these songs I’d written and try very hard to block out everything else.”

Despite the album’s origins in pain, Blumberg has since reconciled with Martin. Speaking about the experience, he noted that while they have reunited, the scars of their time apart are present throughout Minus.

Reconciliation and creative partnership

Following their initial breakup, Blumberg and Martin eventually got back together. They remained a couple for several more years, and their relationship extended into their professional lives.

Martin appeared in the music video for Blumberg’s song “Family,” which was shot in a Parisian hotel room. The video captures an intimate, candid side of the actress. Their relationship also overlapped with their work on the films of Brady Corbet and Mona Fastvold.

Blumberg composed the scores, while Martin acted in the films, creating a unique creative partnership. In fact, they continued to collaborate even after their romantic relationship ended, demonstrating a deep mutual respect.

The final breakup and current relationship status

By March 2025, however, Blumberg and Martin’s relationship had ended. In his March 2025 interview with The Guardian, the actress was referred to as the musician’s ex-partner. However, the outlet also mentioned how the two get on better than ever.

A later interview with Martin from February 2026 further confirmed their status. The article described Blumberg as “Martin’s ex-partner of 14 years”. This indicates that while they are no longer together romantically, they have maintained a positive and supportive relationship.

During their decades-long relationship, they were neither engaged nor married. Likewise, Martin has never been married before dating Blumberg, and she hasn’t gotten married since their breakup. Therefore, Stacy Martin doesn’t have a husband.
