Steve Jones is leaving "The X Factor" stage.
The Fox talent competition host said Monday on Twitter that he wouldn't be returning to host the show's second season.
Jones, a British TV personality, called his departure "a shame" and added that he couldn't "complain as I've had a great time." He gave no reason why he wasn't returning.
Jones was originally slated to host "X Factor" alongside Nicole Scherzinger, who replaced British pop star Cheryl Cole as a judge when executive producer Simon Cowell and other producers had second thoughts about Cole joining the series.
Despite consistent viewership, "X Factor" has failed to achieve popularity similar to "American Idol," which Cowell left to import "X Factor" from the U.K.
The second season is set to debut later this year.
