Days of Our Lives actor Patrick Muldoon had been public about his relationships prior to his death.
The Melrose Place alum’s manager confirmed to Variety in April 2026 that the actor died at age 57. His sister, Shana Muldoon-Zappa, told TMZ that Muldoon had gone to take a shower after drinking coffee with his girlfriend, Miriam Rothbart, in their Beverly Hills home.
After some time had passed, Rothbart checked on him and found him unconscious on the bathroom floor. Paramedics were called to revive Muldoon.
Elisabeth Costa de Beauregard Segel, president of global sales and distribution at Muldoon’s company, Storyboard Media, told Us Weekly, “Heaven got another angel far too soon,” calling Muldoon “the most amazing person.”

Miriam Rothbart
While Patrick Muldoon mainly kept the details of his romance with Miriam Rothbart under wraps, he revealed via Instagram in August 2025 that they had been dating for two years.
“My girl. Two years 2gether today from the night this picture was taken where I got you drunk enough to become my girlfriend,” he wrote. “Thank u 🙏 my ❤️.”
Denise Richards
The pair met in 1997 while filming Starship Troopers, which was released the following year. Patrick Muldoon and Denise Richards dated for nearly five years before splitting around 2000 and remained close friends for years until his death.
“I’ve known Patrick Muldoon since I was 19 years old,” Richards said during a 2019 episode of The Real Housewives of Beverly Hills. “We call each other ‘schweet babe’ because we had nicknames on Starship Troopers for everyone.”
Richards and Muldoon briefly put a pause on their friendship while the actress was married to Charlie Sheen. (Richards and Sheen split in 2006.)
“I did not speak to Pat when I was married to Charlie,” Richards said during a March 2025 episode of Denise Richards & Her Wild Things. “And it was hard, because I didn’t want to lose him as a friend. But toward the end of the marriage, I talked to him all the time about him.”
After her separation from Sheen, Richards married Aaron Phypers — and there were no issues with her friendship with Muldoon.
“Mine and Pat’s relationship romantically was years ago and it’s just a deep friendship,” she said on her Bravo show. “I’m so grateful Aaron respects that because Charlie, he had a hard time with my relationship with Pat.”
During a March 2025 episode of Denise Richards & Her Wild Things, Richards’ daughter Sami Sheen questioned her mom’s friendship with Muldoon.
“He’s very flirty with her, I’m not gonna lie,” Sheen said. “I don’t want to get him in trouble, but I feel like he might still have feelings for my mom. Just an idea.”
Muldoon later shut down the speculation on Tori Spelling‘s “MisSpelling” podcast. “We dated on and off in the ’90s, but since then, it’s been just friendship,” he said during the October 2025 episode, confirming that he was in another relationship.
Tori Spelling
During a 2025 episode of Denise Richards & Her Wild Things, Tori Spelling and Denise Richards talked about Patrick Muldoon being their mutual ex-boyfriend.
“He said he was dating you and could not see you,” Denise recalled. “And I was very jealous.”
Lisa Rinna
Lisa Rinna and Patrick Muldoon had a brief fling while filming Days of Our Lives, which she recalled on a July 2021 episode of the “People in the 90s” podcast.
While opening up about her most “surreal” moment from the decade, Rinna said, “Having an affair with the guy who played my brother. Well, not an affair, but a couple of one-night stands with the guy who [played] my brother. Patrick Muldoon and I had, like, a thing.”
