Inside Jack Antonoff’s dating history: From Lena Dunham to estranged wife Margaret Qualley

Jack Antonoff, the acclaimed Grammy-winning producer and musician, has experienced a series of notable relationships before his recent publicized split from actress Margaret Qualley. Their marriage, spanning three years, ended in mid-2026 amid challenges that reportedly included communication difficulties and differing expectations.

Antonoff's romantic history dates back to his teenage years, when he was linked to fellow student and actress Scarlett Johansson. The two, who attended Manhattan’s Professional Children’s School together, shared a two-year relationship that concluded shortly after high school graduation. This early connection was characterized by youthful infatuation and eventual divergence as Johansson pursued her burgeoning Hollywood career.

In the early 2010s, Antonoff entered a significant relationship with Lena Dunham, the creator and star of the HBO series "Girls." Their five-year partnership began after a blind date arranged by mutual acquaintances, quickly evolving into a serious relationship. However, the couple faced strain following Dunham’s 2017 hysterectomy, which she later discussed candidly in her memoir. The relationship ended amicably in early 2018, and Dunham subsequently married musician Luis Felber.

Shortly after his split from Dunham, rumors emerged linking Antonoff romantically to singer Lorde. The two had collaborated extensively on her 2017 album "Melodrama," with Antonoff producing and co-writing much of the record. Despite public speculation fueled by their close working relationship and shared studio time, both artists firmly denied any romantic involvement, emphasizing a deep professional and platonic friendship instead.

Antonoff’s private life remained relatively discreet until 2018 when he was spotted with model Carlotta Kohl at a New York Knicks game. The couple maintained a low profile throughout their relationship, occasionally appearing together at public events such as the 2021 Grammy Awards, where Antonoff earned Album of the Year for his work on Taylor Swift’s "Folklore." The timeline and reasons for their eventual separation have not been publicly disclosed.

The music producer’s relationship with Margaret Qualley began in 2021, initially observed during a quiet date in Brooklyn before becoming publicly acknowledged at the AFI Awards Luncheon in early 2022. Their engagement was announced just two months later at the Cannes Film Festival, marked by Qualley showcasing a notable diamond ring. The couple’s wedding took place in August 2023 on Long Beach Island, New Jersey, attended by a roster of high-profile guests from both the music and film industries.

Despite the seemingly strong public image of their marriage, signs of trouble emerged by mid-2026. Antonoff appeared at Taylor Swift’s wedding without Qualley, and the two had not been seen together publicly since February of that year. Fans also noticed the absence of a song titled "Margaret" from Bleachers’ tour setlist, a track co-created with Lana Del Rey, which seemed to symbolically reflect the couple’s distancing.

Page Six reported that the couple’s split was influenced by Antonoff’s particular nature and challenges in mutual understanding within the relationship. Nevertheless, Antonoff was still seen wearing his wedding ring after their separation was confirmed, indicating the complexities surrounding their parting.

Throughout his career and personal life, Antonoff’s relationships have often intersected with his creative endeavors, reflecting the intertwined nature of his artistic collaborations and romantic partnerships. While his recent separation from Qualley marks the end of his most private and significant relationship to date, details about his current personal direction remain limited.
