The Recent Dissolution: Prima Apollinaare (Tharita Cesaroni)
The most current and significant news in Dermot Mulroney’s personal life is the end of his marriage to his second wife, Prima Apollinaare. This relationship, which began shortly after his first divorce, was marked by a commitment to privacy and an international flair.
Who is Prima Apollinaare? The Italian Cinematographer
Prima Apollinaare, who is also widely known by her former name, Tharita Cesaroni, is an Italian-born cinematographer and film producer. She was born on February 8, 1973, in Italy, and comes from a creative and artistic family, with her mother being Emi Cesaroni. Unlike her famous husband, Prima has intentionally maintained a low profile, focusing her career behind the camera.
The name change from Tharita Cesaroni to Prima Apollinaare is a key detail, with some sources noting she used her mother’s last name, Cesaroni, previously. She has been described as an Italian musician, though her primary professional focus is in cinematography.
The Timeline of Their Marriage and Amicable Split
Dermot Mulroney and Prima Apollinaare began dating after his separation from Catherine Keener. They quietly tied the knot in 2008, though some reports cite 2010. Their marriage lasted for nearly 15 years, during which they welcomed two daughters:
- Mabel Ray Mulroney: Born in 2008.
- Sally June Mulroney: Born shortly after in 2009.
The news of their separation became public when Mulroney filed for a “standard dissolution of marriage” on June 21, 2025. The actor, who was 61 at the time of the filing, cited irreconcilable differences as the reason for the divorce. Despite the end of the marriage, sources close to the couple have indicated that the split is amicable, and they remain friends, prioritizing the co-parenting of their two daughters. This focus on a friendly separation highlights a maturity in how both Dermot Mulroney and Prima Apollinaare are handling this significant life change.
