It looks like Simon Cowell and Ryan Seacrest will be working on separate shows when Simon leaves American Idol to focus on his new show, X Factor. Simon called in to Ryan's radio show this morning to chat about his new venture, with both men discussing their own futures after eight years together. They confessed to feeling sad about the separation, though Simon admitted it was just time to move on. "I think you've got to know when it's time to go," Simon said. "You know about overexposure, Ryan. I'm on TV too much . . . I genuinely thought people would be sick and tired of me." It was a good run that they shared, but tell us what you think — are you sad to see Ryan and Simon go their separate ways?
