Liam Payne and Niall Horan

One Direction's Liam Payne and Niall Horan have admitted "cow poo" reminds them of home.

The 'Little Things' hitmakers start to feel nostalgic when they get a whiff of manure whilst they're away touring with their band mates - Zayn Malik, Louis Tomlinson and Harry Styles - because the smell of farm animal poop makes them think of their parents' home.

When asked what smell reminds them of home, Niall, 20, told Cosmopolitan magazine: "Cow poo."

Liam, 21, agreed: "I was going to say the same. We both live close to the countryside. Where I live there are farms and you can always smell..."

Niall added: "I'm from the lake district of Ireland so there's the smell of cows and sheep and fresh-cut grass."

Meanwhile, the hunky boy band - who shot to fame after appearing on 'The X Factor' in 2010 - believe they've developed a strong bond, which extends further than just friendship, over the past three years.

Louis, 22, said previously: "I think 'family' is probably the best way of describing us. It's different to friendship."

Niall added: "Yeah, we spend a good time on the road, and, obviously it's so important that we all get along or it won't work."

Harry explained: "There could have easily been one person who didn't get along with anyone; who nobody liked, but it wasn't like that.

"The relationship that's grown with these four boys that I didn't even know three years ago is absolutely insane and it's incredible. I'm very lucky that I get to spend so much time with them."
