Mike Heslin, known for his work in Lioness And The Holiday Proposal Plandied. He was 30 years old.
Heslin’s husband, Scotty Dynamo (born Nicolas James Wilson), shared the news via social media on Friday, July 5, saying the actor passed away on Tuesday, July 2 “from an unexpected cardiac event after a week-long battle in the hospital.”
“Michael was young, perfectly healthy, and doctors have no explanation for what happened,” Dynamo continued.

He shared an Instagram carousel with photos of Heslin at different points in his life, starting with a fairly recent solo portrait. The post also included the couple’s wedding photos and images of Heslin as a child.
Dynamo remembered Heslin as “brilliant, selfless, talented and a true guardian angel.”
The grieving spouse recalled how Heslin helped him “through several bouts of cancer.”
“He was the first person everyone called to share good news, and he was the perfect person to call if you needed a shoulder to lean on or the best advice,” Dynamo said in his lengthy tribute, adding that Heslin was “the sweetest, most caring, most loving man on earth.”

“Michael, meeting you was the best thing that ever happened to me. You are my world. You are my everything. When I felt you take your last breath, my heart broke into a million pieces. If I had the power to trade places with you, I would do it instantly,” he continued.
According to Dynamo, the couple were “on the verge of starting a family” and had even recently started thinking about their “preferred names for our future children.”
His wife added that Heslin’s dream was also to become a donor and that through his death he would be able to offer “the gift of life to four different families.”
Before closing, Dynamo noted that the couple was “3 weeks away from your birthday and 4 months away from our first wedding anniversary.” He concluded his heartfelt message with a Shania Twain quote: “I will love you forever and ever.”
A GoFundMe campaign was launched after Heslin’s death to help cover funeral and hospital expenses, and to provide support to Heslin’s loved ones.
