Sami Sheen mourns mom Denise Richards’ ex-boyfriend Patrick Muldoon’s death

Sami Sheen got emotional as she mourned her mom Denise Richards’ ex-boyfriend Patrick Muldoon’s death on social media.

“Patrick was someone that everyone loved,” she wrote on her Instagram Stories Tuesday alongside the “Wild Things” actress’s tribute to Muldoon.

“He was so quick-witted and humble but still made sure everyone knew he was a rock star and never cared what people thought about him,” Sheen added. “From day 1 till the last day I saw him, he’s never changed.”

The OnlyFans model, 22, penned that she has “been lucky enough to grow up” with the “Melrose Place” alum.

“And I have yet to live my life without him,” Sheen shared.

“The friendship him and my mom had was so beautiful & something not many people get to experience. He will be missed every single day,” she added.

“I hope I wake up from this nightmare soon.”

Sheen then shared another post to her Instagram Stories of a cloud shaped like a heart.

“Right after he passed, I was sitting outside begging for a sign from him to let us know that he’s okay and made it to the other side, and then a couple minutes later I looked up and saw this in the sky,” she wrote alongside the image. “Can’t be a coincidence.”

Muldoon died Sunday following a sudden heart attack. He was 57.

The “Days of our Lives” actor’s sister, Shana Muldoon-Zappa, told TMZ that her brother spent Sunday morning with his partner, Miriam Rothbart, at their Beverly Hills, California, home before going to shower.

When Rothbart went to check on Muldoon, she found him unconscious on the bathroom floor. Paramedics pronounced the actor dead on the scene.

Muldoon dated Richards, 55, for nearly five years in the late ’90s, but had known each other since she was a teenager.

Following news of his passing, the “Real Housewives of Beverly Hills” alum posted a heartbreaking tribute to her “best friend” on Instagram.

“This is so hard for me to put into words. I am deeply heartbroken & devastated losing you,” she wrote alongside a video montage of them together.

“My whole adult life & I don’t know it without you. The friendship, love, support, respect & loyalty we had was unconditional and rare,” Richards added.

The model concluded her tribute, writing, “We thought we’d live forever or at least into our 90’s. Schweetbabe I will be looking for those signs. I need to know you’re still here with me. I love you so much & miss you dearly schweetbabe. 💔🙏🪽.”
