The singer said that his pin-up jacket caught fire near a pyro display in Los Angeles during a live show, reported Sun online.
"It was scary, my arm was on fire. Luckily there was no damage but it could have been a disaster," George said.
The 'I Found You' man isn't the first music star to have an accident with pyrotechnics.
Late King of Pop Michael Jackson suffered burns while shooting a Pepsi advertisement in 1984.
Heavy metal band Metallica mainman James Hetfield meanwhile also suffered burns when a pyro malfunctioned during a gig in Canada in 1992.
