"My family and I are devastated today, by the loss of our young and amazing friend, Cameron Boyce. Years before I was blessed to play his father on JESSIE, we were blessed to know him and his wonderful family at the elementary school our kids all attended together. It was there we were introduced to his endless talent, kindness, and joy for living. At his very 1st talent show, little Cameron's dancing lit up the stage, and left everyone on their feet, cheering . It was clear to all that he was destined to be the star he would soon become. And yet, Cameron never carried himself with anything but kindness, humility, effortless grace, and great humor. Even as his star ascended with JESSIE, and he began to receive the type of fame that can change people, I never saw that change. Not even a little … Our love and heartfelt prayers go out to them, and most especially, to the Boyce family. Your Cameron was a blessing to us, as he was to so many others in this world. May you feel the breadth of love being poured out for him today, and may God comfort you as you mourn." –Charles Esten

"Darling, sweet Cameron. I find this news unfathomable, that a brilliant light such as yours could be gone. I think immediately of your beautiful smile, your infectious energy and your absolutely boundless talent. You, the baby of the crew, so young they were forever pumpkining you out for 'fake Carlos'. To have watched you spin your way through these years with kindness and humility and just begin to come into your own…it is cruel and ugly to see that taken away. I send an ocean of love to your family with whom you were so close and who must be drowning in heartache. As a mother I simply cannot comprehend. It is small comfort that at least you shone more brightly in your few years than most do in a lifetime. Dance through the stars, keep shining. I just still cannot believe." –Keegan Connor Tracy

In fact I was going to message him a couple weeks ago to tell him that I wanted to be in each other's lives more. Now I wish I had sent that message. Just so he personally knew how highly I thought of him and how much admiration I had for him. My heart goes out to his family & his close friends. Cameron, you were and still are a star. May god bless you in heaven. You will be missed down here. –Gregg Sulkin

"I just learned of Cameron Boyce's passing and I am completely, utterly devastated. Cameron has a sweet soul, always was learning, and always tried to pass that knowledge along to others. When I joined the Disney Channel, he became someone I looked up to. Every time I'd see him, hearing something new about the channel, what it meant to be a part of it, and how to navigate the weird world of the job we shared, Cameron always had love to share, but also understanding. He had been through it. All the good, all the bad. All the frustrating parts of it, and all the amazing parts of it. Life is too short, but Cameron's light shines on. I still pass along the things that he told me to kids joining the channel, and hopefully they will do the same." –Joshua Rush
