Angelina Jolie has filed for divorce from her longtime partner Brad Pitt, according to a report.

TMZ reports that the 41-year-old actress and United Nations special envoy filed court papers Monday citing irreconcilable differences as the reason for the split.

The outlet further reports that Jolie was unhappy with the way Pitt, 52, was raising their children. The couple — who married in 2014 but have been together since 2004 — are parents to six children: Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and twins Knox and Vivenne, both 8.

A source close to the couple told TMZ that Jolie was “extremely upset” with Pitt’s parenting methods.

An unnamed source also reportedly told the outlet that Jolie was “fed up” with what the source said was his alleged use of marijuana and anger issues. The source added that Jolie felt the children were in danger around Pitt.

Meanwhile, the New York Post‘s Page Six reports that Jolie had hired a private detective to spy on Pitt on the set of his new London-set movie Allied, where she suspected he had been cheating with co-star Marion Cotillard. The outlet reported that the private eye did catch Pitt cheating with Cotillard.

Page Six also reported several other details related to the split: Jolie reportedly wants to become more involved with her humanitarian work, while Pitt wants to continue to make movies and enjoys Hollywood parties. Jolie appeared at the United Nations just last week to lobby on behalf of Syrian refugees.

The outlet further reported that Pitt is closer to Jolie’s father, actor Jon Voight, than she is: “Jon’s a Hollywood guy, and she’s been estranged. Brad hangs out with her father more than she does,” a source said.

Jolie is reportedly seeking sole physical custody of their six children and asking a judge to grant visitation rights to Pitt.

The couple — dubbed by celebrity tabloid outlets as “Brangelina” — first met on the set of their 2003 thriller Mr. and Mrs. Smith. They recently starred as a couple trying to repair their marriage in last year’s Jolie-directed drama By the Sea.

Jolie has reportedly retained attorney Laura Wasser, who represented actress Amber Heard in her high-profile divorce case against Johnny Depp earlier this summer.
