The Musician's Focus Amidst the Split

While the divorce proceedings began in mid-2025, Prima Apollinaare appears to be focusing on her artistic endeavors. In the same month the divorce was filed, she shared updates on social media, teasing new music collaborations, suggesting she is channeling her energy into her career as a singer-songwriter. Her professional work includes a recent project called *Alignment*, showcasing her multifaceted artistic vision. The couple’s shared appreciation for the arts, with Dermot being a professional cellist and Prima a musician, was a foundation of their long relationship.

A Look Back: Dermot Mulroney’s First Marriage to Catherine Keener

Before his relationship with Prima Apollinaare, Dermot Mulroney was married for 17 years to acclaimed actress Catherine Keener. Their relationship was one of Hollywood’s most enduring, though relatively low-key, partnerships of the 1990s and early 2000s.

The Beginning and End of the Keener-Mulroney Union

Dermot Mulroney and Catherine Keener first met in 1986 while filming the movie *Survival Quest*. They tied the knot in 1990, embarking on a marriage that lasted almost two decades. Keener, known for her Oscar-nominated roles in *Being John Malkovich* and *Capote*, and Mulroney, famous for his romantic lead and character work, were a quintessential Hollywood power couple. The couple separated in May 2005, and Dermot officially filed for divorce in June 2007, citing irreconcilable differences. Their divorce was finalized in 2008, paving the way for Mulroney's subsequent marriage to Prima Apollinaare later that year.

Their Son: Clyde Keener Mulroney

Dermot and Catherine share one son, Clyde Keener Mulroney, who was born in 1999. Following in the footsteps of his artistic parents and his father’s musical talent, Clyde has established himself as a singer and musician. His career trajectory is a testament to the creative environment he was raised in, bridging the acting world of his mother and the musical passion of his father.

The Common Threads in Mulroney’s Marital Journey

Dermot Mulroney’s two marriages, though distinct, share several commonalities that speak to the actor’s personal life priorities:

1. Commitment to Creative Partners

Both Catherine Keener and Prima Apollinaare are highly accomplished women in the creative arts. Keener is a revered actress, while Apollinaare is a musician, cinematographer, and producer. This suggests Mulroney is drawn to partners who share a deep, professional commitment to the artistic world, a world he himself inhabits as both an actor and a cellist.

2. Emphasis on Privacy

Both relationships were notably private by Hollywood standards. Mulroney and Keener kept their family life out of the tabloids, and his marriage to Prima Apollinaare (Tharita Cesaroni) was even more low-key, with his wife often using a professional moniker. This pattern reflects a concerted effort by Mulroney to shield his family from the intense media scrutiny that often accompanies a celebrity lifestyle.

3. A Focus on Family

Dermot Mulroney is a father to three children across his two marriages: Clyde, Mabel Ray, and Sally June. The reports of his June 2025 divorce being "amicable" underscore a desire to maintain a friendly co-parenting relationship with Prima Apollinaare, mirroring the cordial relationship he maintained with Catherine Keener following their divorce, all prioritizing the well-being of their children. As Dermot Mulroney navigates this new chapter of his life following the June 2025 divorce filing, his professional career remains robust, with upcoming projects like the 2025 film *Killing Mary Sue*. His personal journey, marked by two long-term marriages to talented women, continues to be a compelling story for his fans.
