Update: Source says the bus was carrying members of Cyrus' family and not part of the singer's "Bangerz" tour

A tour bus carrying members of Miley Cyrus' family was charred in a dramatic fire overnight on the road, but don't worry -- everyone escaped unharmed. In footage posted by the pop star's sister, Noah, the bus is seen engulfed in flames and a closeup image shows its gutted interior.

"Bus down!" Noah Cyrus tweeted, later telling concerned fans that "everyone got out safe… everything is okay!!"

Miley Cyrus was apparently not on the bus, which was actually her mom Tish's and not part of the pop singer's "Bangerz" tour, a source with knowledge of the situation tells Billboard. According to the source, the fire was started due to a blown tire. 

The exact location of the incident is unclear at this time, however, Tish Cyrus and family were en route to New Orleans for tonight's "Bangerz" show there.

Miley Cyrus performed in Houston on Sunday and has shows lined up through April.
