• His death was announced on Friday after a 'week long battle in the hospital'

Mike Heslin passed away earlier this week at the age of 30, his husband Scotty Dynamo shared on Friday.

He revealed that Heslin, who is known for appearing in 2023 thriller series Lioness, died on July 2 after an 'unexpected cardiac event' and a 'week long battle in the hospital.'

Dynamo said 'the doctors have no explanation for what happened' as his husband was 'young' and 'in perfect health.' 

He also said because his husband wanted to be a donor, he had 'given the gift of life to four different families.'

Dynamo also revealed they began the 'early stages of starting a family together' a week ago and had been picking out baby names.

Heslin appeared in two episodes of Lioness and acted in various television series including In Their Shoes: A Journey to Homelessness, The Influencers, House Sitting, I Love You... But I Lied, Younger and 7 Deadly Sins. 

He also played a role in 2023 rom-com The Holiday Proposal Plan and 2020 TV movie Boy*Friends. 

In his post, Dynamo — who has been with Heslin since 2018 and married him less than a year ago in November 2023 — shared a carousel of photos and penned a tearjerking eulogy gushing about his beloved husband.

The grieving spouse noted that Heslin died three weeks from his 31st birthday and four months from their first wedding anniversary. 

He said his husband would have been the 'world's most perfect father,' adding that if he 'ever [became] a dad,' he would name his son after him.

He continued to say that he hopes he would be able to 'manage to raise him to become at least half the man you are.' 

He said his dearly departed husband, who he also called his 'best friend and soulmate,' was 'truly was the sweetest, most caring, and loving man on earth.'

Addressing Heslin, he wrote: '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,' he continued. '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 said Heslin was 'brilliant, selfless, talented, and a real-life guardian angel' and 'single-handedly carried me through multiple rounds of cancer' after he was diagnosed with testicular cancer in the fall of 2020. 

'He was the first person everyone would call to share good news with, and he was the perfect person to call if they needed a shoulder to lean on or the best advice,' he wrote.

'Michael, meeting you was the best thing to ever happen to me. You are my world. You are everything to me,' he also wrote.

'I know that you are in a better place and that heaven has gained another angel.'

At the end of his letter, he concluded, 'Michael, in the words of Shania Twain: I'll love you "forever and for always."'

A GoFundMe campaign was set up to help cover funeral and hospital costs as well as provide support to Heslin's loved ones.
