Pixie Lott and Katie Perry join X Factor panel
Chart-topping singers Katy Perry and Pixie Lott are to join the next series of The X Factor as guest judges, it has been announced.
The duo, with Australian singer Natalie Imbruglia and Spice Girl Geri Halliwell, will stand in for mother-to-be Dannii Minogue, who is due to give birth in July, during the audition shows around the country.
Simon Cowell, Louis Walsh and Cheryl Cole will reprise their roles on the panel for the seventh series of the award-winning show, and Minogue will join them for the judges' house stage of the competition later in the year.
Halliwell kicked off the first auditions in Glasgow, while Imbruglia will appear at the Birmingham auditions tomorrow and on Monday.
