Denise Richards' ex-boyfriend, Patrick Muldoon addressed rumours of having feelings for her while dating his low-key partner, Miriam Rothbart.
Actor and producer, Patrick Muldoon passed away on Sunday morning, April 19, 2026. He was 57 years old at the time of his untimely death. Patrick was a popular face of 1990s television and film, best known for his roles in Days of Our Lives, Starship Troopers, Melrose Place, and Saved by the Bell. His demise broke the hearts of his fans, friends and his family. According to reports, Patrick is survived by his partner, Miriam Rothbart, his parents, his sister, Shana Zappa, his brother-in-law, Ahmet Zappa, and their children, niece, Halo and nephew, Arrow Zappa. Here's everything we know about his private life with his ladylove.
Miriam Rothbart was named as the surviving partner of Patrick Muldoon. She has largely remained out of the public spotlight, even as the girlfriend of an accomplished Hollywood star. The public first learned of Miriam's existence when he opened up about her during his appearance on the October 2025 episode of iHeartRadio's MisSPELLING podcast. It was the first time the actor spoke about his personal life since his split with Denise Richards. At that time, Patrick revealed that he had been secretly dating his girlfriend for two years since 2023.
Patrick didn't immediately unveil her identity to the public as she likely wants to avoid the excessive media attention that comes with being associated with a celebrity. Later, his secret girlfriend's name was revealed to be Miriam Rothbart. However, nothing regarding her age, background, or dating timeline with Patrick is publicly known. However, based on the revelation of the now-late actor, he started dating her after taking a hiatus from acting following his 2022 movie, Dakota. Notably, Miriam hasn't issued any official statement regarding the death of her long-term partner, and neither have fans been able to locate her social media accounts.
During a March 25, 2025, episode of the reality series, Denise Richards & Her Wild Things, her eldest daughter, Sami Sheen (who was 21 back then) jokingly remarked that her mother's ex-boyfriend, Patrick Muldoon, might still have feelings for Denise. Charlie Sheen's daughter made the comment while watching Denise and Patrick's undeniable on-screen chemistry in one of his music videos, where her mother played his love interest. Sami even playfully stated that Patrick was "very flirty" with Denise, which made her wonder if her mom still had a special place in his heart. Sami clarified that she didn't want him to take public flak for her comments, as she was just sharing her observation. She mentioned:
"He's [Patrick Muldoon] very flirty with her [Denise Richards], I'm not gonna lie. I don't want to get him in trouble, but I feel like he might still have feelings for my mom. Just an idea."
Seven months after Sami Sheen's remarks about Patrick still having feelings for his ex, Denise, he broke the silence on the buzz during the October 2025 episode of iHeartRadio's MisSPELLING podcast. He addressed Sami's "wishful thinking," clarifying that while he and Denise are "very tight buddies," they have been purely platonic since their on-and-off relationship ended in the 90s. Explaining their long-standing history and reason for mutual affection, Patrick mentioned there was a misconception that the duo met on the set of Starship Troopers, when in reality their connection went way back.
According to Patrick, he and Denise bonded over their shared background as outsiders in the film industry. They first met in an acting class when she was in her teens, and he was in his early twenties. The ex-couple naturally grew close and became each other's support system while they struggled to make a name for themselves in Hollywood. Recalling their good old days together and refuting having feeling for her while he was dating his girlfriend, Miriam Rothbart, Patrick said:
"The thing about Denise and I is everybody thinks we met on Starship Troopers, but we met in acting class when she was 19 and I was 21. We both don't come from entertainment families, and our families got to know each other over the years and kind of checked in with each other on navigating the crazy stuff that we all go through."
