Miley Cyrus' tour bus burst into flames while her mother and sister were on board.

The Wrecking Ball singer and her entourage were travelling to New Orleans on Monday night for the next instalment of her Bangerz world tour when one of the vehicles in the convoy spontaneously combusted.

The 21-year-old star's younger sister Noah Cyrus and her mother were on board at the time, with the 14-year-old teen sharing the news via a series of videos posted on Instagram, captioned "Tour bus down!"

She later confirmed on Twitter that no one had been hurt, writing, "Yes, everyone got out safe no one is injured what so ever!! everything is okay!! (sic)"

TMZ has confirmed the blaze was caused by an exploding tyre and not by church protesters who disagree with Miley's radical image setting the bus on fire, as fans were quick to speculate.

It appears the only casualty was a toy bunny rabbit belonging Miley's mum, with Noah jokingly sharing a digitally-altered image of a stuffed animal with flames emerging from its head.

She added: "Bunny down! Moms toy bunny burnt down in the fire!

Cyrus has attracted controversy for her X-rated live shows, which see the former Hannah Montana actress simulating a sex act on a man wearing a Bill Clinton mask and writhing around provocatively on the bonnet of a car.
