Nicole Scherzinger will put her X Factor judging hat back on when she returns to the show as a guest judge on Wednesday.
The ex-Pussycat Doll previously performed the role on the UK show in 2010 and last year she replaced Cheryl Cole in a permanent position on The X Factor USA - before she was also axed by Simon Cowell.
Now, holding no grudges, Nicole will step back onto the UK panel alongside Gary Barlow, Louis Walsh and Tulisa to judge at the final London auditions this week.
She wrote on Twitter:
On Monday, Rita Ora was the guest judge on the show, standing in while producers hunt for someone to replace Kelly Rowland. HuffPost UK were given a behind the scenes look at the audition process yesterday and saw Rita in action.
Meanwhile, former X Factor winner Leona Lewis will act as a guest judge on Tuesday.
Over the weekend, Spice Girl Geri Halliwell made an appearance as a guest judge at the Liverpool auditions. Despite her best efforts, Gary Barlow wasn't keen on her taking a seat on the panel permanently.
