Michael Clifford, guitarist for the band 5 Seconds of Summer, was set on fire Saturday night when a fireball engulfed him on stage.
The London concert included pyrotechnics where fire would shoot from portions of the stage. Michael was standing too close when a ball of flames lit his hair on fire, badly burning his face.
The show had almost ended -- the band was about to do an encore - but the show abruptly ended and Michael was taken to the hospital.
Michael tweeted that his condition is stable, adding, "What the f***s up. sorry I couldnt finish the encore but at least I look like two face, thanks for worrying."
Here's the craziest part ... he says he's feeling better and he's performing tonight.
