5SOS SMOKING DANGER!A big whoops from 5 Seconds of Summer star Calum Hood.
According to the Daily Telegraph, the 19 year old band member was photographed smoking a lit cigarette on the weekend - at a petrol station.
He was with some mates on Saturday when they filled up their car, ciggie in tow.
That's definitely what you call unwise, given the danger factor of flammable liquids near a spark.
This is what BP says on its website: "Petrol is a volatile, highly flammable liquid that gives off vapours. It's important to never smoke, light a match or stub a cigarette out, especially around pumps or fuel containers. You also shouldn't leave cigarettes burning in your car’s ashtray."
Calum then hung with fellow bandmate Luke Hemming on the weekend, while the rest of 5SOS are already in LA.
