She replaces Kylie Minogue (who initially replaced Jessie J) joining Tom Jones, will.i.am and Ricky Wilson on the coaching panel for the BBC One show. Presenters Emma Wilis and former JLS singer Marvin Humes will all return. The Voice UK launches in January 2015.
This may tie in nicely with her album release in January 2015. After all, she does have quite a strong fanbase over in the UK. Not sure why she would turn down X Factor for a lower tier version but then, all of these shows have gone down the drain in general.
