According to singer Hillary Scott's post on social media, the bus was transporting Hillary, her husband and her tour manager when it blew a tire.
"Our bus tire caught on fire and we had to evacuate very quickly," she posted. "Everyone is safe and sound."
All four onboard were able to escape the fire without injury.
"It was me, my husband, our tour manager, and driver," Scott posted. "Thanking God for our safety and the safety of all of those who helped put this fire out and keep us safe."
Publicist Mary Hilliard said the bus is not Hillary's usual bus and did not say why Scott's usual bus was unavailable.
