(CNN) -- Reality singing competition "The X Factor" has lost its flagship star and its place on Fox's lineup. On Friday, judge Simon Cowell announced he was leaving the American version of "The X Factor" to return to the original UK iteration, news that came as Fox confirmed "The X Factor" is being canceled after three seasons. "Unfortunately, there is no 'X Factor USA' without Simon Cowell, but we understand and support his decision to focus on the international formats and on the next phase of his personal life," Fox Broadcasting's chairman of entertainment, Kevin Reilly, said in a statement. "We wish him the very best, and it's our sincere hope that we work together again soon."
