Jessie J has fuelled more speculation that she will not be returning 'The Voice' UK after announcing tours dates that clash with filming.

The 'Domino' singer recently revealed on twitter she was to kick off a 12-date UK tour in February 2013.

However the shows are due to take place at the same time filming for the second series is expected to take place.

BBC1 boss Danny Cohen has expressed his wishes for the 24-year-old star to return with Sir Tom Jones, will.i.am and Danny O'Donoghue next year.

But Jessie J has refused to confirm whether she will be back as mentor for contestants.

A BBC insider said yesterday: ''It is too soon to know what might happen with next year's show.''

Meanwhile the performer told radio station Capital FM: ''This tour is the tour that I've been waiting for.

''It's so exciting to know that I'm going to step out onto some of the biggest arenas around the UK and hoping that they'll be rammed with crazy fans singing and screaming - I can't wait to give them a performance they'll never forget.''
