Nicole Scherzinger is to return as the latest guest judge for 'The X Factor' auditions.
The former Pussycat Dolls singer will join the panel for the final London heat tomorrow.
Scherzinger previously appeared on the panel in 2010 when she stood in for then judges Cheryl Cole and Dannii Minogue.
She joins a succession of guest judges who have joined the series this year until a permanent fourth judge is found to sit alongside Gary Barlow, Tulisa Contostavlos and Louis Walsh.
Yesterday, chart-topping star Rita Ora impressed show bosses and the audience when she featured on the panel, although she may not yet have a high enough profile to clinch the deal. Her busy schedule may also affect her availability and she is only able to sit on the panel for a few hours today because of gig commitments as she tours with Coldplay.
Show insiders say it is looking increasingly unlikely that another guest judge, Geri Halliwell, will be given the role full time, although producers have still to make up their minds.
Past X Factor winner Leona Lewis was joining the panel again this afternoon after first sitting on at the weekend.
Scherzinger said of her return to the panel at the O2 Arena in London tomorrow: “I’m super excited to be back in London for The X Factor.
“Last time I was here we found One Direction and I can’t wait to find more unique and interesting talent here in the UK.”
Auditions move to Manchester next week.
