The band had to cancel their show as Michael was rushed to hospital. #5SOSFam across the world were sending message of support in their millions, with Michael staying as the top trend on Twitter all night.

Bandmate Calum Hood was also apparently burned - with his arm touching the on-stage flamethrower.

Michael took to Instagram in the early hours of this morning to let everyone know that he was doing ok, but we were SO worried!

We're sure Mikey will make a full recovery, especially with his awesome bandmates by his side!

No one ever wants to see your best friend in the state I saw mike backstage. He's a trooper and is ok.

The boys clearly didn't want to risk playing with fire again, so the on-stage flamethrowers were replaced with confetti cannons for their final London show.
