American actor Cameron Boyce has died at the age of 20, his family has confirmed.
The Disney star, known for his roles in the Descendants franchise and the TV show Jessie, passed away in his sleep after suffering a seizure, which was a result of an "ongoing medical condition".
A spokesperson confirmed the news in a statement on behalf of the Boyce family, which read: "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.

They added: "We are utterly heartbroken and ask for privacy during this immensely difficult time as we grieve the loss of our precious son and brother."
Boyce was born in Los Angeles and made his acting debut aged nine in the horror film Mirrors in 2008.
His breakthrough role was on the Disney television show Jessie in which he played Luke Ross, one of the leading characters. It ran for four season from 2011 to 2015.
He became best known for playing Carlos, son of villain Cruella De Vil, in 2015's Disney TV movie Descendants and the sequel in 2017. He also starred in the Adam Sandler films Grown Ups and Grown Ups 2.

"His talent, immeasurable. His kindness and generosity, overflowing. It has been an indescribable honor and pleasure to know and work with him. I will see you again in all things loving and beautiful my friend.
"I will search the stars for your light. Rest In Peace Cam."
Boyce's Grown Ups co-star Adam Sandler penned an emotional tribute to the late actor.
"Too young. Too sweet. Too funny. Just the nicest, most talented, and most decent kid around," Sandler wrote.
"Loved that kid. Cared so much about his family. Cared so much about the world. Thank you, Cameron, for all you gave to us. So much more was on the way.
"All our hearts are broken. Thinking of your amazing family and sending our deepest condolences."
A Disney Channel spokesperson said in a statement: "From a young age, Cameron Boyce dreamed of sharing his extraordinary artistic talents with the world.
"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.
