Last night Rachel Stevens appeared on X Factor New Zealand and twitter went in ablaze after her role as a mentor at judges houses was over. Many claiming they want her to replace one of the female judges on the show. Do you think this was a look to see how well she could work on the show, as a UK Replacement in the future. Remember mentoring is not about vocal skills but experience and how you help an artist progress. Rachel showed that last night, with her critiques and observations! Should she do the show ?
