Simon Cowell
Simon Cowell, who discovered One Direction on the UK's "X Factor" in 2010, said he never could have predicted the boy band would get so big.

When asked by MTV News at the premiere of the Fox version of the show if he could have imagined their success, he said,"No! I mean, you know, I thought they would work as a band, but you can't predict these kinds of things," he told MTV News at the premiere of the second season of the Fox version of the show, which kicked off this week.

"But it's down to them," he continued, crediting the guys for putting in the effort to be successful. "They've worked hard. They work really well as a group. The records are good. They're nice guys to work with. So the world, right now, is theirs."
