The 33-year-old presenter has revealed she will not be returning to 'The X Factor' spin-off show after just one year as host due to clashes with other work commitments.

She wrote on Twitter: Xtra Factor has been amazing, however I have a new project coming up this summer. And with all the changes happening, I won't be back...

"But I'm so excited to see the new line up and wanna wish them all the luck in the world ... Can't wait to watch them in action! (sic)"

The news comes after Dermot O'Leary was axed as host of the main show with former 'Xtra Factor' presenters Caroline Flack and Olly Murs hired as his replacements.

Louis Walsh has also been sacked from the judging panel as part of the show's revamp and it was decided Sarah could no longer give the show the attention it needed.

A source told the Daily Mirror newspaper: "Sarah had two different meetings with 'X Factor' bosses and lots of discussions this week. Everyone decided that this was the best outcome.

"Sarah is really looking forward to the projects she is going to be starting this summer."
