Actor Cameron Boyce, best known for his roles on the Disney Channel shows "Descendants" and "Jessie" has died. He was just 20 years old.

The cause of death was announced as due to "an ongoing medical condition."

A spokesperson had the following to say on behalf of the Boyce family:

It is with a profoundly heavy heart that we report that this morning we lost Cameron. He passed away in his sleep due to a seizure which was a result of an ongoing medical condition for which he was being treated. The world is undoubtedly without one of its brightest lights, but his spirit will live on through the kindness and compassion of all who knew and loved him.

Boyce, who was from Los Angeles, made his acting debut in the horror film "Mirrors" when he was just nine years old. A couple of years later he appeared in the Adam Sandler flick "Grown Ups" as one of Sandler's children.

Most know him from his role on the Disney Channel show "Jessie." He starred as Luke Ross alongside the lead character Jessie Prescott, played by Debby Ryan. That show ran for four seasons and 98 episodes.

Boyce would catapult even higher on the Disney Channel hierarchy with his role in the popular "Descendant" films, which led cable TV film ratings in 2015 and 2017.

The young actor was also heavily involved in charity work, having been honored with the Pioneering Spirit Award at last year's Thirst Gala, sponsored by the Thirst Project, a nonprofit Boyce raised $30,000 for to build wells for clean drinking water in Swaziland.

“From a young age, Cameron Boyce dreamed of sharing his extraordinary artistic talents with the world. As a young man, he was fueled by a strong desire to make a difference in peoples’ lives through his humanitarian work,” said a Disney Channel spokesperson. “He was an incredibly talented performer, a remarkably caring and thoughtful person and, above all else, he was a loving and dedicated son, brother, grandson and friend.

“We offer our deepest condolences to his family, cast mates and colleagues and join his many millions of fans in grieving his untimely passing. He will be dearly missed.”
