Harry Styles' old pal: We caused chaos

Harry Styles' childhood friend Will Sweeney has revealed that the pair acted 'like complete idiots in public.'

Harry shot to fame with his boy band One Direction in recent years.

Before he was famous, the superstar pop singer partook in unruly boy activities with his buddies.

'We'd act like complete idiots in public. Harry would go into Tesco, pretend he had Tourette's and walk around screaming and shouting,' Will told British newspaper The Sun.

'We'd throw things at each other, we'd just create chaos and a bit of a mess. We were told off by security and customers.

'We played this game where you pick something up and launch it over your head without knowing where the other person is - and they've got to try to catch it.

'We grabbed all sorts - bread, sauces - and Harry dropped stuff everywhere.

'Harry and I got told off at Waitrose once because we were screaming 'Bogies!' as loud as we could.

'We would each scream 'Bogies!' louder than the other person, we would shriek until we were blue in the face.

'Harry loved it. He was always up for fun, wacky things, having a laugh, and he never cared what people thought.'
