Lena Dunham Admits She Cheated on Jack Antonoff—With Her Childhood Boyfriend

Lena Dunham just dropped a bombshell confession: she cheated on Jack Antonoff near the end of their five-year relationship. And not with just anyone—with a childhood boyfriend.

The “Girls” creator opened up about the affair during a recent interview, revealing that she slept with the ex from her past while still with the music producer. According to the report, this happened toward the tail end of their romance, which ended in 2021.

Dunham didn’t hold back when discussing the infidelity, giving specific details about how it all went down. The admission is pretty candid coming from the usually guarded filmmaker, who’s known for keeping her personal life relatively private in recent years.

This is the first time Dunham has publicly addressed cheating in the relationship. The revelation is bound to raise eyebrows, especially since she and Antonoff had seemed pretty solid during their time together. Their split was initially reported as amicable, but this new info suggests there was more drama brewing behind the scenes than anyone realized.
