Liam gets hold of Harry's jeans

Liam Payne decided to give band mate Harry Styles a bit of a shock during their gig at the O2 Arena on Saturday night.

The cheeky One Direction singer, 19, yanked down Harry‘s trousers as he sang his solo part of What Makes You Beautiful.

Harry, 19, quickly pulled his jeans back up over his skimpy black pants – which looked like a jockstrap design – but the screaming crowd had already manage to cop a good look.

Professional Harry managed to carry on with the performance and later proved he wasn’t angry by bending over and flashing his sexy undies to the audience again.

Despite his fans going crazy at the sight of his kecks, the curly-haired heartthrob insists he doesn’t understand why people find him so attractive.

‘I don’t think I can ever get used to any amount of attention I get,’ Harry tells The Sun.

‘In no way am I a sex symbol, definitely not.’
