Country Star Jerrod Niemann -- Flips Out After Tour Bus Explodes

Country superstar Jerrod Niemann-- the guy who sings "Lover, Lover" -- is lucky to be alive ... after his tour bus caught fire and then exploded after a performance in Tennessee.

According to reports, Niemann -- along with his band, his father and his uncle -- had just got on the bus when his friend Lee Brice warned everyone about a possible fire on board. 

Everyone quickly got off the bus ... and a short time later there was an explosion followed by a fireball that engulfed the back of the bus.

As the bus was burning, Jerrod, Lee and another friend whipped out their middle fingers and took a pretty rock star pic in front of the blaze. Jerrod later tweeted, "Thank the good Lord that @leebrice was here tonite or I'd be Freddy Krueger."

Officials are still investigating the cause of the blaze.
