Mulroney and Apollinaare showed off their chemistry when they appeared together on Fox's We Are Family in February 2024, performing Dolly Parton and Kenny Rogers' hit track Islands in the Stream.
"It was such an amazing phone call to get that the show reached out to us," Mulroney told Entertainment Weekly at the time. "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. Kind of a stealth Hollywood couple. So it really works perfectly for this show."
Mulroney Filed for Divorce From Apollinaare After 14 Years of Marriage

After 14 years of marriage, the Point of No Return star filed for divorce from Apollinaare on June 21.
According to court documents obtained by an outlet, Mulroney cited irreconcilable differences as the reason for the split. He also listed the date of separation as "TBD."
The About Schmidt star is seeking joint physical and legal custody of their daughters, as well as spousal or domestic partner support payable to himself. Additionally, Mulroney is requesting that the court be prevented from awarding support to his estranged wife.
"No one is asking for anything, and no one is denying anything," a source told EW. "They are not arguing over the children nor money. They used mediators, not lawyers, as they are friends and this is amicable. They were advised to file this way which seems to have caused media confusion."
