Louis Walsh has admitted he is worried that his may be his last year as an X Factor judge.

The Irish music manager has been on the show since it began and is about to join the panel for the ninth time.

However, he is concerned that his luck may be running out and that Simon Cowell will axe him before the 2013 series.

Walsh told The Sun: "I can't believe it is my ninth year on X Factor.

"But I really don't know if I'll make it to ten.

"If I work hard, I'll get the job. If not, Simon will let me go."

He added: "It's going to be hard work this year, really hard work. Simon will be cracking the whip.

"He makes the best shows but nobody is safe to stay. If I don't make ten years I'll have a lot on next year anyway.

"I'm going to manage Shane Filan's solo career after Westlife split up."

Walsh and Gary Barlow have so far been confirmed as judges for the upcoming series.

Kelly Rowland is not coming back and it is still uncertain who her replacement will be.
