Rita Ora And Avril Lavigne Rumoured To Be The X Factor’s Final Judge Former Spice Girl Geri Halliwell may have been given the chance to impress Simon Cowell as a judge at the first X Factor auditions in Liverpool this week, but if she wants the job permanently she’d better watch her back because a host of stars including Avril Lavigne and Rita Ora are reportedly in contention for a judging role on the TV talent show. Speculation has been rife as to who’ll fill the shoes of Kelly Rowland, who left the show after one series. Former judge Dannii Minogue was thought to be being lined up, but the Australian beauty reportedly decided against rejoining at the last minute.According to The Daily Star, Lavigne could be set to take a permanent spot on the panel. Surprisingly given that she’s relatively new to stardom, Ora is also reportedly being thought of as a potential judge.One thing that could work in Ora’s favour is the perceived success of potential colleague Tulisa Contostavlos, who joined the judging panel herself when relatively young.Other guest judges who are reportedly lined up are Robbie Williams and Rod Stewart. However a permanent judge will be needed by the time filming starts for the judges’ houses later this year.It is unlikely to be Williams, at least in this series, as Take That bandmate Gary Barlow is already on the panel. Joining Gary and Tulisa is veteran judge Louis Walsh, with the identity of the fourth judge sparking fierce speculation.Other rumoured potential judges include soulful singer Alicia Keys and Gwen Stefani.
