Singer Miley Cyrus and her family members and band colleagues were unhurt early Tuesday following a tour-bus fire on the way to New Orleans.

"Tour bus down!" wrote her younger sister, actress Noah Cyrus, 14, around 1:40 a.m., captioning her Instagram video of a highway fire. Shortly afterward, she posted video of a smoldering wreckage, with Larry Rudolph, Miley Cyrus' manager, narrating, "This is the bus we were riding on -- was the bus we were riding on. I don't think it's a bus anymore."

Rudolph, Noah Cyrus and the girls' mother Tish Cyrus (but not Miley), had been passengers, said Us Weekly, which reported that a blown tire started the fire and that no one was injured. "Thank u God for keeping us safe," Noah had tweeted about an hour and a half before posting the videos.

Miley Cyrus remained scheduled to perform Tuesday night at the Smoothie King Center in New Orleans.
