Walsh's 'X Factor' future depends on Sharon

X Factor judge Louis Walsh has vowed that he will only sign up for the second series of the show if Sharon Osbourne does.

Sharon and Louis have grown close since the live shows began, and are regularly seen ganging up against their fellow judge, Simon Cowell.

Walsh told The Mirror, "Sharon is the star. I'd only do another series if she was in it. I'll work with Simon again but on my terms."

Both judges are apparently expecting an extra £250,000 to stay for another series.
