Michael Clifford is fine after he was burned in onstage mishap

Michael Clifford, a vocalist and guitarist with the Australian pop rock band 5 Seconds of Summer, tweeted he is fine after his hair caught on fire during a show in London Saturday night.

The 19-year-old musician joked online -- shortly after he accidentally walked into the stage pyrotechnics -- that he now looks like the Batman villain Two-Face with his half-bandaged mug.

"sorry I couldnt finish the encore, but at least I look like two face. thanks for worrying every1 x," he said in a Twitter post.

"If I obviously don't want to have my picture taken right now please don't take my picture :) see everyone tomorrow!!" he said in a later tweet.
