Chicago Fire actor Dermot Mulroney has filed to divorce his wife of 15 years, musician Prima Apollinaare.

Mulroney, 61, signed a petition to dissolve the marriage June 21, according to People. He cited irreconcilable differences and didn’t list a date of separation.

Mulroney, who appears to be representing himself, also requested attorneys' fees be split between he and Apollinaare. He also asked for joint physical and legal custody of their daughters: Mabel Ray, 17, and Sally June, 15.

The Scream actor also requested spousal support from Apollinaare and asked for the termination of the court’s ability to award her financial support.

Apollinaare and Mulroney shared a love of music and even worked together on several projects. Mulroney, a professional cellist in addition to his film and TV work, is credited in Planet of the Apes and some of the Mission: Impossible franchise.

He was previously married to actor Catherine Keener from 1990 to 2007. They share a son, Clyde Keener Mulroney.
