Jack Antonoff link resurfaces as Lena Dunham’s ‘Famesick’ reveals messy split

Lena Dunham’s new memoir Famesick is drawing fresh attention, with revelations about her past relationship with Jack Antonoff emerging as one of the book’s most talked-about threads.

The Girls creator revisits the breakdown of their relationship, describing a turbulent period marked by health struggles, emotional strain and growing distance between the pair.

She writes that tensions escalated as Antonoff spent increasing time with a “teen pop star” he was working with, recalling a moment where the singer was seen crying in his lap at their home.

Relationship strain and blurred boundaries

Following a major argument after Dunham underwent surgery, the couple agreed to take a break while still living together. Dunham suggests the boundaries of their separation were unclear, hinting that both sides navigated the situation differently.

During this period, she admits to entering into an affair with a childhood friend. The relationship intensified quickly, leading to an engagement within a month, before ultimately ending as Dunham confronted addiction and entered rehab.

Claims about Adam Driver

Elsewhere in Famesick, Dunham makes allegations about her Girls co-star Adam Driver, describing him as at times “verbally aggressive, condescending and physically imposing”.

She claims that during one rehearsal he threw a chair against a wall, while also recalling moments where he was supportive during periods of anxiety. By the show’s final season, she writes that the two had grown distant.

Fallout with Jenni Konner

The memoir also explores Dunham’s fractured friendship with Girls producer Jenni Konner, which she describes as increasingly toxic before their eventual split in 2018.

She recounts a final therapy session between the two that ended abruptly, marking the end of their relationship both personally and professionally.

Health struggles and regret

Dunham details her health challenges, including a hysterectomy and subsequent dependency on pain medication, which led her to seek treatment in rehab.

She also revisits backlash over a joint statement defending Girls writer Murray Miller against sexual assault allegations, saying she has no memory of writing it and expressing regret over the harm it caused.

With Famesick, Dunham offers an unfiltered account of a difficult chapter in her life, revisiting relationships, controversies and personal struggles that continue to shape her public image.
