When she worked on The X Factor, Nicole said it was Liam Payne who was uncertain about joining a group. She told Pop Justice (via PressParty): "When I put the group together, Liam was hesitant about it because he wanted to go solo."
Um...can you imagine One Direction without Liam? Yeah. We don't even want to think about a world like that. As for her prediction about who she thinks will leave One Direction first to try a solo career, well, no surprises there. She thinks it will be Harry Styles. And given the almost daily rumors about Harry quitting One Direction, it's not a huge shocker.
