Margaret Qualley and Jack Antonoff file for an uncontested divorce in New York, months after their summer separation

'The Substance' star Margaret Qualley, 32, and 14-time Grammy-winning producer Jack Antonoff, 42, jointly filed for an uncontested divorce in Kings County Supreme Court, Brooklyn, on Friday. The split was described as "a mutual decision," with the pair set to remain "lifelong friends." They had no children.

Separation rumours began when Antonoff attended Taylor Swift and Travis Kelce's July wedding alone, bringing his sister Rachel instead of Qualley.

Reps denied infidelity, saying "there are no trust issues" — but reportedly "communication was definitely a challenge" and Qualley felt her perspective wasn't being heard.

At a September concert Antonoff quipped "Read the news, brother" when a fan requested he play 'Let's Get Married.'
