Billy Ray Cyrus, who along with his daughter Miley grew close to the Travolta family during filming and promotion of Bolt, has spoken about the death of Jett, who, at 16, was the same age as his daughter.

"Our thoughts and prayers are with John and his family," he told E! News Sunday afternoon on a sidewalk near his L.A. home. "They're great human beings and strong people. And, again, our thoughts and prayers are with him and his family."
