Liam Payne once locked lips with Zayn Malik.

The 21-year-old singer and the 22-year-old hunk - who, along with their other One Direction bandmates Harry Styles, Niall Horan and Louis Tomlinson, are often the subject of fans fictional stories in which they embark in relationships with each other - revealed they have shared a sneaky smooch which Zayn encouraged.

He said: ''I ended up kissing Zayn once! Zayn was like, 'Come on then, come on,' putting his head close to me.

''It was like when you're going to have a fight. Then he just leaned forward and kissed me.''

Louis, 23, admitted he is not as fussy as Liam about which of the band members he would embrace, while Harry wasn't able to make his mind up when asked.

When quizzed about which of his bandmates he would kiss in a life or death situation, the 21-year-old star told We Love Pop Magazine: ''I can't answer that. I genuinely can't.''

Louis added: ''I'd probably snog all the guys, to be honest.''

It's not the first time One Direction have shared a smooch with each other as in the video for the band's 2013 single 'Kiss You' Zayn jumps on Harry's back and gives him a little kiss on the cheek.
