Simon Cowell considering The X Factor return as he warns the judges they're not safe!

Simon CowellSimon Cowell has hinted that he might return to The X Factor UK, after warning the judges that their jobs aren’t safe for the next series!

According to The Mirror, the 52-year-old has rated Kelly Rowland, Tulisa Contostavlos, Gary Barlow and Louis Walsh a ‘could do better’ eight out of ten for their work last year, claiming they didn’t push their acts hard enough.

He also criticised the foursome for failing to do ‘enough different things’ as mentors, citing Cheryl Cole’s work with Cher Lloyd as an example.

And it appears that all four are now in the firing line – even Cowell’s old friend and rival Walsh, who has been with the show since it started.

“We have got to look at everyone, the whole show. I don’t know if I will keep the panel the same. I haven’t decided yet,” the media mogul revealed.

“Judging can be tough, but if we can’t find a star out of 120,000 applicants then someone isn’t doing their job properly.”

Although he reiterated his commitment to the American X Factor, claiming it’d be tricky to keep flying back and forth across the Atlantic, Simon added that he’d reconsider a return to the UK version of the show.

He has already re-joined the panel of Britain’s Got Talent, which recently begun filming its sixth series.
