After fifteen years of marriage and a commitment to privacy, actor Dermot Mulroney and musician Prima Apollinaare have officially parted ways, finalizing an amicable divorce away from the glare of the cameras.

In a town famous for its messy, high-profile breakups, Dermot Mulroney and Prima Apollinaare have chosen the road less traveled: dignity. The veteran actor, best known for his charming role in My Best Friend's Wedding, has finalized his divorce from his wife of 15 years, the Italian singer-songwriter Prima Apollinaare. The settlement, reached in January 2026, draws the curtain on a relationship that began in 2008 and produced two daughters. Unlike the courtroom dramas that dominate the tabloids, this split was handled with the quiet grace of two people who simply drifted apart.

Irreconcilable Differences

Mulroney filed for divorce in June 2025, citing the standard "irreconcilable differences." Court documents reveal that the couple had been separated for some time before the legal machinery was set in motion. Despite the end of their romantic union, the pair opted for private mediation to resolve the details of their split, avoiding a public trial. It is a move that speaks volumes about their priority: protecting their teenage daughters, Mabel Ray and Sally June.

The final judgment details a joint custody agreement, ensuring that both parents remain active figures in their children’s lives. “They didn’t just want to win; they wanted to parent,” a source close to the family noted. The division of assets and spousal support was also settled amicably, a rarity in Hollywood divorces where forensic accountants are usually the busiest people in the room.

A Pattern of Privacy

Throughout their marriage, Mulroney and Apollinaare kept a low profile. They were rarely seen on red carpets together, preferring a quiet life away from the paparazzi swarms. This desire for privacy has extended to their divorce. There were no tell-all interviews, no cryptic social media posts, and no mudslinging. Just a quiet signature on a legal document.

• The "Grey Divorce" Trend: Their split reflects a growing trend of long-term couples parting ways later in life. As they enter a new phase, both seem focused on their respective crafts—Mulroney on his acting, and Apollinaare on her music.
• Moving On: For Mulroney, this is his second divorce (having previously been married to Catherine Keener), but his reputation as a "good guy" in Hollywood remains intact. He continues to work steadily, proving that personal upheaval need not derail a professional legacy.

As they go their separate ways, Mulroney and Apollinaare leave behind a blueprint for how to end a marriage with respect. It may not be the fairy tale ending fans hope for, but in the real world, a peaceful goodbye is sometimes the best happy ending one can ask for.
