Cameron Boyce who starred in kids' comedy series Jessie and the film Grown Ups, died in his sleep last night.
The actor passed away after suffering a seizure as a result of an ongoing but undisclosed medical problem, his family confirmed.
A family spokesman said: "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 now 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.
"We are utterly heartbroken and ask for privacy during this immensely difficult time as we grieve the loss of our precious son and brother."
A Disney Channel spokesman described Boyce as an “incredibly talented performer”.
They said: “From a young age, Cameron Boyce dreamed of sharing his extraordinary artistic talents with the world.
“As a young man, he was fuelled by a strong desire to make a difference in peoples' lives through his humanitarian work.
"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."
