Cameron Boyce's 'Descendants' Co-Star Sofia Carson: 'Letting You Go Is Not Something I Know How to Do'

Sofia Carson, who starred with the late Cameron Boyce in Disney Channel's "Descendants" franchise, has broken her silence on the young actor's untimely death.

A week after Boyce, 20, died of a seizure in his sleep, Carson wrote on Instagram, "To our angel, There are not enough words.There will never be enough words. I couldn't bring myself to do this because doing this makes it real. Letting you go is not something I know how to do. And I just can't fathom living in a world without you. I love you, Cam. And I will love you. Forever."

Her words were accompanied by a balletic, black-and-white image of Boyce in mid-leap.

Fellow actress Dove Cameron, who has already expressed her grief over Boyce, replied, "i love you," and "Descendants" director Kenny Ortega wrote of the image, "I'm soaring, flying, there's not a star in heaven that I can't reach."

Disney Channel has canceled the July 22 premiere of "Descendants 3," saying in a statement, "We're proud to be part of Cameron Boyce's legacy by showcasing his talents on screen, but we are cancelling the red carpet premiere event for 'Descendants 3.'"
