UPDATE (6/14/15, 4:34 p.m. ET):

A 5 Seconds of Summer spokesperson confirmed to MTV News that Clifford is healing but ready to take the stage at the band's next show: "Michael is recovering well after being given the all clear by doctors. He will join the band on stage tonight at The SSE Arena for their third and final London show. Michael and the band would like to thank all the fans, well wishers and particularly last night's audience for their support. There will be no pyrotechnic production for the show this evening."

Meanwhile, the guitarist is keeping up his sense of humor through it all. Three hours ago, he updated his Twitter prof pic to one of him caught mid-flame.

5 Seconds of Summer guitarist Michael Clifford suffered burns to the head on Saturday night (June 13) when he accidentally walked into a pyrotechnic display onstage.

The Aussie band was playing their smash hit “She Looks So Perfect” during their second night playing Wembley Arena in London when Clifford’s hair caught on fire.

In this clip captured by a fan, the 19-year-old can be seen scrambling offstage and fanning away the smoke with a towel.

Following the incident, Clifford’s bandmate Ashton Irwin took the mic and told the crowd they wouldn’t be continuing the show.

“Michael has hurt himself so we will not be continuing the show right now,” Irwin said. “Just want to say thank you so much for coming. He is OK. You guys have been the best crowd we could ask for tonight. Thank you so much.”

While 5SOS fans were understandably worried, Clifford later took to Twitter to assure them he’s OK, sharing a selfie with bandages covering the burnt side of his face.

5SOS bassist Calum Hood also tweeted about the incident, calling Clifford a "trooper."

MTV News has reached out to the band for more information.
