Former Spice Girl Geri Halliwell is reportedly set to act as a guest judge on 'The X Factor' this year.
According to The Mirror, the singer will attend tomorrow's Glasgow auditions with Simon Cowell, Louis Walsh and Cheryl Cole.
A source said: "Geri has told Simon she can spice up the audition process."
"She worked with Louis on 'Popstars: The Rivals' when Cheryl auditioned, so it will be interesting to see what their chemistry is like."
Halliwell will reportedly be sitting in for regular judge Dannii Minogue, who is currently on maternity leave.
