One Direction's Liam Payne shows off his body in just a pair of pants in the band's new teaser trailer for upcoming film 'This Is Us'.

The chart-topping band - also comprising Niall Horan, Harry Styles, Zayn Malik and Louis Tomlinson - are starring in the hotly-anticipated 3D documentary movie which captures their meteoric rise to fame since appearing on The X Factor in 2010.

The band are building even more hype ahead of the film's release in August with a series of teaser trailers.

The latest clip sees Styles going back to his former part time job at his local bakery, where he jokes around with the older female staff.

Payne also shows off his body in just a pair of pants as he cheekily tells the camera to "keep the lens up here" as he's putting on his trousers.

One Direction are currently on their 'Take Me Home' world tour.
