Still, Dermot Mulroney has stated that all community earnings and accumulation during marriage through the date of separation” will be considered community property.
Dermot Mulroney and Prima Appollinaare’s relationship timeline explored as the duo files for divorce
Dermot Mulroney was previously married to Catherine Keener before they split in 2007. The duo shares a son, Clyde. In 2012, Muloney, 61, appeared on The Rosie Show, where he discussed moving on after his divorce from Keener:
“A lot of it doesn’t make sense, but you can’t deny your heart.”
A year after the actor’s divorce from Keener, he was linked to Prima Apollinaare, born Tharita Cutulle. In 2008, the pair welcomed their first daughter, Mabel Ray.
Mabel was baptized in October 2008 at San Pietro, Italy. In 2009, their second daughter, Sally, was born. The actor tied the knot with the Italian singer and actress in December 2010.
The My Best Friend’s Wedding actor told The Hollywood News in 2016 that parenting wasn’t “straight and narrow.”
He added:
"I try to keep the arts in front of them, whether it's music or even just museum trips. I don’t expect anything of them—it’s hard enough for everyone just to get their homework done at night."
In February 2024, Dermot Mulroney and Appollinaare appeared together on Fox’s We Are Family and served as the series’s first married couple. They performed Islands in the Stream by Dolly Parton and Kenny Rogers together.
Delmot Mulroney told Entertainment Weekly that he and Appollinaare were excited to be invited on the show:
“It was such an amazing phone call to get that the show reached out to us. They knew Prima’s music and put together that we are this sort of secret couple, even though we’ve been together for 20 years,”
He added:
"Kind of a stealth Hollywood couple. So it really works perfectly for this show.”
According to People, a source close to the couple has revealed that their split is amicable and there are no financial arguments between them.
