Singers Katy Perry and Nicole Scherzinger are the big names in consideration to fill Kelly Rowland’s spot in Britain’s ‘The X Factor’. Rowland, who had been on the judges panel last season, has left the show and now the organisers are in search for a new judge, Daily Express reported. “I’ve worked with Nicole and Katy before and I would love to work with them again, they were fantastic,” said Louis Walsh. According to reports, five celebrities are in contention with Melanie Brown, Anastasia, current ‘X-factor’ judge in Australia, and Sharone Osbourne who has previously been a judge on the show. “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,” Walsh added. Started in 2004, ‘X Factor’ will soon go on air for its season 9.
