5 Seconds of Summer band member Michael Clifford's face caught on fire during a concert in London due to some pyrotechnics gone wrong. Clifford was quickly taken to the hospital where he was treated and tweeted to fans, ""What the f---s up. sorry I couldn't finish the encore but at least I look like two face, thanks for worrying." Luckily, he's making a full recovery and is continuing the tour. Yikes!
