Who is Dermot Mulroney’s wife Prima Apollinaare? The Italian singer whose private life couldn’t save her 14-year marriage

Actor Dermot Mulroney has officially filed for divorce from singer-songwriter Prima Apollinaare, marking the end of their 14-year marriage. According to court documents obtained by TMZ, the My Best Friend’s Wedding star cited “irreconcilable differences” and is requesting spousal support from Apollinaare while asking that she not receive any support in return.

The couple, who share two minor daughters, Maybel Ray and Sally.

This is Mulroney’s second divorce; he was previously married to actress Catherine Keener, with whom he shares an adult son, Clyde.

Mulroney and Apollinaare were first linked in 2008, shortly after his separation from Keener. Their relationship became public the same year they welcomed their first child.

They married in December 2010 and were known for keeping a relatively low profile, though they occasionally collaborated musically. In 2024, the pair performed together on FOX’s We Are Family, with Mulroney.

Despite the personal and professional bond they once shared, the divorce filing suggests the couple has reached a breaking point. As news of the split circulates, attention has turned to Prima Apollinaare herself, a multifaceted artist with an international background.

Who Is Prima Apollinaare?

Prima Apollinaare, born Tharita Cutulle into a musical family, is an Italian-born musician known for her soulful vocals and introspective songwriting. She legally changed her name in 2015, according to TMZ.

Raised in Italy with a diverse cultural background, she described herself as “75 percent Italian” and “15 percent Argentinian” in a 2023 interview. Her mother was a singer, and her father played the trumpet and piano, influences that clearly shaped her own artistic path.

Apollinaare stepped into the spotlight as a solo artist in 2017 with the release of her debut single Stand Up for Love.

In the same interview, she said her favorite part of being a musician is simply the act of singing and playing, though she noted that limited time and resources can be a challenge.

Despite personal upheaval, Apollinaare appears to be channeling her energy into her art.

In June 2025, she shared an update on Instagram, teasing new music in collaboration with producer Eren Cannata. “Can’t wait for you to hear it,” she wrote.
