The former All Saints singer is joining Louis in France for the judge's houses round of the auditions, according to The Sun.
Nicole recently split from her rock star husband Liam Gallagher amid allegations he has fathered a child with another woman, which could be the reason 'X Factor' bosses have snapped her up for the show.
Nicole, 38, will help former Westlife manager Louis pick the best of the Under 25 boys to go through to the live finals of the ITV talent show.
Last year Louis was helped by Sharon Osbourne, but this year she has returned to the judging panel and is mentoring the Over 25 category.
It has been revealed that Sharon's return to the judging panel helped boost viewing figures for the show by 500,000.
