Band members Liam Payne, Louis Tomlinson, Niall Horan and Harry Styles played down the jeering received by Malik when his face was shown at their concert, despite a video that proved it happened, reported Aceshowbiz.
"It's the first we've heard of it," Tomlinson said, while Payne, 21, said "I don't think that's true, if I'm honest."
"We had a gig in Cardiff last night and it was amazing. We haven't done a gig in a while and to then come back to that," Horan, 21, added.
This moment was captured by one of the fans who posted the video on micro-blogging site Twitter.
Zayn, 22, left One Direction in March earlier this year to live a "normal" life.
