One Direction’s Niall Horan has had an embarrassing problem exposed by his fellow band mate.

During an interview with Top of the Pops magazine ‘Midnight Memories’ star Zayn Malik took the opportunity to reveal Niall’s flatulence issues.

Zayn said: “He doesn't like me telling people, but Niall farts the most out of everyone! The thing with him is that they're really noisy, but they don't actually smell that bad. They're kind of bearable - or I might have become immune to them! It's just like really loud air coming out of his bum.”

21-year-old Malik continued to reveal One Direction’s immature side as he also admitted that the group still have a soft spot for playing with toys:

“We're all big kids when it comes to toys and stuff. We have big lightsabers, a few toys and an Iron Man mask. We just like messing about with toys, but I think we're past the teddy bear stage now, haha! But lightsabers are cool.”

One Direction recently unveiled their latest video ‘Midnight Memories’ which sees the boy band driving around on mobility scooters and visiting a kebab shop.
