Miley Cyrus -- My Tour Bus Burst Into Flames!

Miley Cyrus' tour bus went up in flames last night ... and when we say up in flames ... we mean UP IN FLAMES.

Miley's sister Noah posted a series of videos on Instagram last night with the caption "Tour bus down!" She later confirmed on Twitter that no one was injured.

Miley was traveling to New Orleans, where she is scheduled to play a show tonight.

9:20 AM PT -- The tour bus was ferrying Miley's mom and sister before it burst into flames. We're told the fire was caused by a tire that exploded, but thankfully, they both escaped unharmed.

There was one casualty however -- the stuffed bunny they got at Cracker Barrel earlier in the day. Noah Instagrammed the bunny photo after the accident.
