Michael Clifford suffered burns to the head during an on-stage accident while performing in London Saturday night with his band, 5 Seconds of Summer, footage showed.
According to footage captured by fans at the Wembley Arena, Clifford was singed when he walked into a pyrotechnical display of fire shooting up from the stage.
He can be seen quickly dabbing his face with a towel before scrambling off stage.
Smoke could be seen coming off the singer's head.
"Michael has hurt himself so we will not be continuing the show right now," his bandmate told the crowd. "He is ok."
5SOS fans were left distraught by the footage:
Clifford later tweeted this image showing his face in bandages.
He tweeted on Sunday morning that he had recovered and was set to take to the stage again.
