Actor Mike Heslin has died aged 30

His husband announced his passing on social media.

Heslin starred as Polo in two episodes of Lioness on Paramount+, which was directed by Taylor Sheridan (Yellowstone) and also stars Zoe Saldana and Nicole Kidman.

His husband, Nicholas James Wilson (who goes by the handle @scottydynamo on Instagram) announced his death in a heartbreaking post last night and wrote a lengthy tribute to his "husband, best friend, and soulmate".

"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. Michael was young, in perfect health, and the doctors have no explanation for what happened," he wrote.

"He moved through life with such ease and confidence, and turned everyone around him into a better version of themselves," he added. "No matter how difficult things got, we knew that there was nothing we couldn’t overcome with Mike in our corner.

"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.

"Just a week ago, we were in the early stages of starting a family and would regularly share our favorite baby names for our future kids. You always told me that you felt like you were meant to be a dad, and I couldn’t agree more. You would be the world’s most perfect father. If I ever become a dad, I am going to name my son after you and hope that I manage to raise him to become at least half the man you are," he continued.

"You were the most generous and giving person. 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. We are 3 weeks away from your birthday and 4 months shy of our 1 year wedding anniversary, but I know that you are in a better place and that heaven has gained another angel.

"Michael, in the words of Shania Twain: I’ll love you 'forever and for always'."
