Lena Dunham's forthcoming memoir, "Famesick," contains recollections about her nearly six-year relationship with music producer Jack Antonoff, which have gained attention following the news of Antonoff's split from Margaret Qualley. The memoir, slated for release in 2026, details Antonoff's interactions with an unnamed "teen pop star" during his relationship with Dunham.
Dunham, in "Famesick," writes about FaceTiming Antonoff, whom she dated from 2012 to late 2017, while he was in their shared apartment's recording studio with a young pop artist. She described him as being "ensconced with a teen pop star I was too oblivious to be jealous of." In another passage, Dunham recounts returning from a doctor's appointment to find the pop star "sprawled across our sectional couch, weeping into Jack’s lap as he told her that ‘your teens are for experimenting’ in a tone so comforting, it almost brought tears to my eyes." She noted that it had been a long time since Antonoff had spoken to her with such "expansive generosity."
Fans have speculated that the unnamed singer was Lorde, with whom Antonoff collaborated on her 2015-2016 album "Melodrama." At the time of their collaboration, Lorde was between 18 and 19 years old. Antonoff addressed rumors of infidelity in 2018, stating on X (formerly Twitter) that he was not seeing anyone and emphasizing the importance of his professional and personal relationships. Lorde also publicly denied dating Antonoff via Instagram Live in February 2018.
Dunham's memoir also touches on a significant argument between her and Antonoff concerning her pain medication following a hysterectomy. According to the memoir, Antonoff responded by flushing her medication down the toilet, which necessitated a call to her doctor and an urgent pharmacy trip to prevent withdrawal symptoms.
These revelations from Dunham's memoir come to light shortly after Page Six exclusively reported that Antonoff and Qualley were separating. The couple, who married in August 2023, reportedly faced challenges in their marriage, with a source suggesting communication issues and Antonoff's particular way of doing things. Qualley had also quietly removed photos of Antonoff from her Instagram page prior to the breakup announcement and did not attend his July 3 wedding to Travis Kelce.
