Making music can be some seriously sweaty work - just ask Niall Horan.

The One Direction singer was outed by his bandmates for getting naked in the recording studio.

Niall revealed: "I like to take my top off. It can get really hot in the studio.

"I recorded What Makes You Beautiful in my boxers!"

The Irish charmer was also blamed for making the worst smell on the tour bus.

Louis Tomlinson joked that most of the lads laugh or crack a smile if they fart but said Niall remains stone faced.

Or at least until his eyes start watering.

Meanwhile, keeno Directioners who’ve pre-ordered album Midnight Memories on iTunes will receive three extra tracks next week, exclusively ahead of its release on November 25.
