Mike Heslin, the actor best known for “Special Ops: Lioness,” has died. He was 30.

His husband, Scotty Dynamo, announced the tragic news on Instagram Saturday.

Dynamo said that Heslin died of “an unexpected cardiac event,” but that “doctors have no explanation for what happened.”

“On July 2nd, my husband, best friend, and soulmate @mikeheslin passed away from an unexpected cardiac event after a week long battle in the hospital,” Dynamo began his post.

“Michael was young, in perfect health, and the doctors have no explanation for what happened,” he added.

The recording artist called Heslin a “brilliant, selfless, talented, and a real-life guardian angel” and credited the late actor with helping him get through cancer.

“He truly was the sweetest, most caring, and loving man on earth, and he brought out the absolute best in everyone who had the pleasure to cross paths with him,” Dynamo wrote. “He moved through life with such ease and confidence, and turned everyone around him into a better version of themselves. No matter how difficult things got, we knew that there was nothing we couldn’t overcome with Mike in our corner.”

He continued: “Michael, meeting you was the best thing to ever happen to me. You are my world. You are everything to me. When I felt you take your last breath, my heart shattered into a million pieces. If I had the power to trade places with you, I would do it in an instant. But I will take it one day at a time like you always told me to, and live every day in your honor.”

Dynamo also revealed that the couple — who tied the knot in November 2023 — “were in the early stages of starting a family” before Heslin’s death.

“You were the most generous and giving person,” Dynamo added. “It brings me peace to know that, through your wish to be a donor, you have given the gift of life to four different families. I know that you are in a better place and that heaven has gained another angel.”

A GoFundMe page has been set up to cover Heslin’s funeral and hospital costs. Over $58,000 has been raised as of Sunday.

“There are many ways to define a person and their impact, and Mike is many beautiful things to so many people. But the word we keep returning to is Helper. In that Mike spirit, it’s time for us to be the Helpers,” a message on the page reads in part.
