The One Direction boys love to prank poor Harry Styles during his What Makes You Beautiful solo and this time Liam Payne gave fans a thrill by pulling down Harry's jeans.
The screams of the 20,000 fans in this YouTube video shows just how much they appreciated Liam's cheeky prank.
We just love the bit where Louis lends a helping hand and takes Liam's micrphone so he is completely free to get a proper grip on Harry's trousers.
Poor Harry has had a lot of drama in his private areas during the tour so far after getting hit in the balls with a microphone and the flying shoe that also managed to find its way to his balls.
We do hope that all these moments make the cut in their flick, This Is Us!
Will you be watching the lads in their upcoming flick?
