On May 27 a video of Zayn Malik smoking a suspicious roll-up was leaked online, with Louis Tomlinson giggling and appearing to talk in the background, reported Daily Mirror.
"Harry Styles is annoyed about the whole debacle. This should be one of the biggest weeks of the band's career with the launch of their UK stadium tour. Instead it has been taken over by this controversy. Harry thinks it was a stupid and reckless thing for Louis to allow to be filmed in the first place," a source said.
The footage emerged while the group are in the midst of the UK leg of their Where We Are Tour and the remaining members of One Direction - Harry, Niall Horan and Liam Payne - were not present in the short clip.
