Katy Perry may be joining hubby Russell Brand on this side of the pond, as she is favourited to replace judges Simon Cowell and Cherly Cole on X Factor UK.

Cowell and Cole have announced they will be focusing on the US version of the show, leaving an open panel position here in the UK. Perry is front-running to nab the spot with 7/2 odds, according to bookmakers William Hill, while Gary Barlow and Sharon Osbourne trail behind at 4/1.

Perry has already made an impression on X Factor fans after guest hosting the audition stage last year.

Said spokesman Joe Crilly: “Katy Perry was very well liked when she appeared on last year’s show and the odds suggest that she is in pole position to either take over from a departing judge or become a fifth judge on the show.”

Other celebrity hopefuls for the judging position include Robbie Williams, Nicole Scherzinger, Paula Abdul, and Michael Buble. X Factor producers said they hope to have a decision made by the end of February.
