Kylie was saying the other day she would love to come back to the UK next year, but she goes straight into coaching and filming the The Voice Australia live shows, which will run till first week of Aug and has touring scheduled, so she's not sure if she can fit another series in back to back. Ricky has said he would like all 4 to remain, and he is right as the ratings have shown this year was definitely the best of the 3 so far in the UK. Kylie and Ricky were much better than Jessie J and Danny, even will.i.am was good this year and Tom Jones just owns that show with the fans. The early blinds and auditions were a little slow, but it really took off with the Live shows.
