Brendon's family announced on social media on Friday he had died in his sleep and that his death was from 'natural causes'.

"We are heartbroken to share the passing of our brother and son, Nicholas Brendon. He passed in his sleep of natural causes," they wrote alongside photos of Brendon through the years.

"Most people know Nicky for his work as an actor and for the characters he brought to life over the years. In recent years Nicky has found his passion in painting and art.

"Nicky loved to share his enthusiastic talent with his family, friends and fans. He was passionate, sensitive, and endlessly driven to create. Those who truly knew him understood that his art was one of the purest reflections of who he was."

Brendon had also been candid about past struggles with addiction and mental health.

His family added in their statement: "While it’s no secret that Nicholas had struggles in the past, he was on medications and treatment to manage his diagnosis and he was optimistic about the future at the time of his passing.

"Our family asks for privacy during this time as we grieve his loss and celebrate the life of a man who lived with intensity, imagination, and heart. Thank you to everyone who has shown love and support."

Sarah Michelle Gellar – who recently revealed why the Buffy reboot has been abruptly canceled – has paid tribute to her former co-star in the wake of his death.

Gellar, 48, shared a photo to her five million followers on Instagram as she paid tribute.

She wrote: "They’ll never know how tough it is to be the one who isn’t chosen. To live so near to the spotlight, and never step in it. But I know. I see more than anybody realizes, because nobody’s watching me."

She added: "I saw you Nicky. I know you are at peace, in that big rocking chair in the sky."
