Margaret Qualley and Jack Antonoff have reportedly 'jointly' filed for divorce

Margaret Qualley and Jack Antonoff have reportedly filed for divorce.

The pair went their separate ways in July after almost three years of marriage, and a source has now told People that divorce proceedings were initiated on Friday (30.10.26).

The insider explained that Margaret and Jack "are filing for divorce jointly".

They explained that while New York State requires one party to be a plaintiff and the other to be the defendant, actress Margaret, 32, and 42-year-old singer-songwriter Jack's separation is amicable and mutually agreed, adding: "This is a mutual decision."

The source went on: "They share a deep affinity and love for one another, and though their romantic partnership is ending, they will absolutely be lifelong friends."

In July, questions were raised about their relationship after the Bleachers musician was accompanied to pop megastar Taylor Swift, 36, and 37-year-old Kansas City Chiefs tight end Travis Kelce's wedding by his sister Rachel, rather than his wife.

And it was reported a few days later that they had gone their separate ways.

A spokesperson for the Substance star subsequently spoke out to address some of the claims surrounding their split, insisting Margaret and Jack have nothing but "deep love and care" for one another.

The representative said: "The narratives running in the press about Margaret and Jack are categorically untrue. There are no trust issues. There was no infidelity or anything outside of respect and partnership in this relationship.

"They have deep love and care for one another. There are only two people in this marriage, and the sources who are talking to the press and commenting on their relationship are not people who know them."
