The Wet singer, who has been replaced by Demi Lovato and Britney Spears on The X Factor USA, will take her seat on the UK panel at the next round of auditions at London's O2 Arena tomorrow (30th May).
Confirming the news, a tweet on the show's official Twitter account read: "The gorgeous @NicoleScherzy will be Guest Judge at tomorrow's auditions. (Which start at 11am, punctuality fans)."
Scherzinger herself also tweeted: "Super excited to be back in London for @TheXFactor! Can't wait to find more unique and interesting talent!"
She later added: "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."
The announcement comes after former guest judge Geri Halliwell's future as a permanent judge was thrown into doubt, with reports claiming she lacked chemistry with fellow panellists Tulisa, Louis Walsh and Gary Barlow.
R.I.P. singer Rita Ora impressed crowds in London yesterday (28th May), while former XF champ Leona Lewis will return to guest judge today. Spice Girls star Mel B is also rumoured to make an appearance at the Manchester leg of auditions later this week.
