Judge, creator and executive producer of the U.S. version of "The X Factor" Simon Cowell is a guest on "Piers Morgan Tonight" this evening at 9pmET/PT, ahead of the launch of the new show tomorrow. "It is the biggest moment of my career," Cowell tells Piers Morgan. "I kind of knew what I was getting involved in before we did this, but you're never quite prepared for it."
Cowell also compared the U.K. hit version with this new American version.
"It has its own personality," he said. "And I've been quite cautious about saying to people how they're going to feel about it...you've got to discover this show."
Watch the full interview tonight 9pmET/PT – also on the show, his fellow judge Nicole Scherzinger.
