There are reported to be five celebrities being considered for former Destiny Child star Kelly Rowland's job.
Amongst the celebrities being considered are Katy Perry and Pussycat doll Nicole Scherzinger. Louis Walsh told the Irish Herald newspaper, "I’ve worked with Nicole and Katy before and I would love to work with them again, they were fantastic."
Also being considered for the position are current X Factor Australia judge and former Spice Girls star Melanie Brown, singer Anastasia, and ex-judge Sharon Osbourne.
Confirmed judge Louis Walsh said: "Mel B knows the format so well... Anastasia has sold millions of records and is a big star and I would give anything to work with Sharon again."
Irish Louis currently judges the show with Take That's Gary Barlow and pop star Tulisa Contostavlos.
If pop princess Katy Perry were to take on the role, it would mean leaving rumoured new lover, Florence and the Machine guitarist Robert Ackroyd. Katy is said to have fallen head over heels for the tattooed musician, and was seen enjoying public embraces with him recently. Robert soon started following the singer on Twitter, and it appears they've now fallen for each other. Katy announced her split from Russell Brand at the end of December after 14 months of marriage, and their divorce is scheduled to come through in July.
