Angus Cloud, who rose to fame playing Fezco in Euphoria, has died aged 25.
"It is with the heaviest heart that we had to say goodbye to an incredible human today. As an artist, a friend, a brother and a son, Angus was special to all of us in so many ways," his family said in a statement released to TMZ.
"Last week he buried his father and intensely struggled with this loss.
"The only comfort we have is knowing Angus is now reunited with his dad, who was his best friend.
"Angus was open about his battle with mental health and we hope that his passing can be a reminder to others that they are not alone and should not fight this on their own in silence."
They added at the end: "We hope the world remembers him for his humour, laughter and love for everyone.
"We ask for privacy at this time as we are still processing this devastating loss."
There has been an outpouring of grief from friends and fans on Cloud's Instagram page.
"RIP Legend. Gone but never forgotten. Euphoria won’t be the same without you," one person wrote.
Another added: "I’m so sorry, rest easy my love."
A third said: "Thank you for everything sleep in peace."
Cloud is best known for playing warmhearted drug dealer Fezco on the HBO teen drama Euphoria from 2019 and until 2022.
The 25-year-old was born and raised in Oakland, California to Irish parents and had planned to move to Ireland before becoming involved in the world of film and TV.
He studied set-building and lighting at Oakland School for the Arts.
“I just liked the hands-on [stuff],” he told NME last year. “It seemed cool, and I think I had a few buddies doing that, so I just jumped in [too]."
After he graduated, he moved to New York and started working at a chicken-and-waffles restaurant in Brooklyn.
He hadn't considered acting until a casting agent named Jennifer Venditti spotted him on the street and thought he'd be perfect for the role of Fezco.
In an interview with Variety last year, Cloud said people often assume he's just like his character in real life.
“It does bother me when people are like, ‘It must be so easy! You get to go in and be yourself.’ I’m like, ‘Why don’t you go and do that?’ It’s not that simple," he told the publication.
"I brought a lot to the character. You can believe what you want. It ain’t got nothing to do with me.”
He also worked on two other projects that are yet to come out.
