The X Factor team certainly are rolling out the stars this week!

In just a few dates of auditions, they have already seen Geri Halliwell sitting in Kelly Rowland’s old seat when the tryouts hit Liverpool and this week, in London’s O2 Arena both Rita Ora and Leona Lewis took the fourth spot on the panel alongside Gary Barlow, Tulisa Contostavlos and Louis Walsh.

Rita and Leona will return today, with Ora judging in the morning session and Lewis taking on the hopefuls this afternoon but at tomorrow’s auditions there will be another old favourite at the table.

ITV have confirmed that Nicole Scherzinger will be back on Wednesday and wrote on their Facebook wall:

Nicole Scherzinger will be Guest Judge at tomorrow’s auditions!

On her return to the show, the brunette beauty said:

“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.”

Of course Nicole is no stranger to The X Factor, having filled in for both Dannii Minogue and Cheryl Cole back in 2010. Her one day stint on the series then, turned into a longer run when Cole fell ill with malaria and she ended up working with the hopefuls through the whole bootcamp stage.

She assisted Simon Cowell and Louis Walsh in putting together teen supergroup One Direction during those sessions.

Nicole also judged on last year’s series of X Factor USA along with Paula Abdul, Cowell and L.A Reid but was sacked from that panel earlier this year.
