Dermot Mulroney Files for Divorce from Wife Prima Apollinaare After 15 Years

Dermot Mulroney has filed for divorce from his wife, Prima Apollinaare.

According to court documents obtained by PEOPLE, the 61-year-old actor signed a petition to dissolve his 15-year marriage on Saturday, June 21. Mulroney, who appears to be representing himself, cited irreconcilable differences and listed their date of separation as “TBD.”

The Chicago Fire actor also asked that attorneys’ fees be split between them, and that they share joint physical and legal custody of their two daughters: Mabel Ray, 17, and Sally June, 15.

Additionally, Mulroney requested the termination of the court’s ability to award Apollinaare spousal support, but requested spousal support for himself.

However, a source tells PEOPLE, “No one is asking for anything, and no one is denying anything. They are not arguing over the children nor money.”

“They used mediators, not lawyers, as they are friends and this is amicable,” the insider adds. “They were advised to file this way.”

While the pair has not fully established “the nature and extent” of assets, Mulroney stated that “all community earnings and accumulation during marriage through the date of separation” will be considered community property. 

Mulroney met Apollinaare a year after his divorce from actress Catherine Keener.

Mulroney and Apollinaare started dating in 2008 and welcomed their first daughter that same year. Shortly after, they had their second daughter before officially tying the knot in December 2010.

The couple first bonded over their shared love for music — along with acting, Mulroney is a professional cellist with credits in movies such as Planet of the Apes and some in the Mission: Impossible franchise, and Apollinaare is a singer-songwriter.

Apollinaare, who changed her name from Tharita Cutulle for unknown reasons in 2015, is originally from Italy. Although she hasn’t shared much about her childhood, she has said that music was always her passion.

“[I] got into music since I was born,” the songstress told the music label Lost In The Manor in 2023. “My mom is a singer. My dad played Trumpet and piano.”

Apollinaare and Mulroney have worked together in the past.

She has also joined her soon-to-be ex on some of his film projects. In 2010, she was listed as one of Mulroney’s producing partners for a biopic he was set to direct, per the Associated Press (via The Hollywood Reporter).

Later that same year, Mulroney revealed to the New York Post that Apollinaare was not a fan of his horror movies, like Scream IV.

“I don’t think she’ll probably even see this movie because I know what her tolerance is,” he said. “She can’t even look at half of the posters.”
