5 Seconds Of Summer guitarist Michael Clifford had a scary accident during Saturday night's concert.
While performing in London, Clifford's head caught on fire after he walked into one of the onstage pyrotechnics. He quickly ran away to put it out, but the show was cut short. You can watch the mishap in the video above.
"Michael has hurt himself so we will not be continuing the show right now. He is okay," drummer Ashton Irwin said.
Later, Clifford addressed fans in a series of tweets.
