Jessie J’s future as a coach on the BBC talent show The Voice has been thrown into doubt by reports that she has quit.

The Domino hitmaker is said to be leaving before the second series of the show as her forthcoming UK tour will clash with filming dates.

Meanwhile, despite claims Sir Tom Jones - whose contestant Leanne Mitchell won the show - will also depart the programme, he insists he wants to stay, but only if he is happy with his fellow coaches.

He told TV host Rob Brydon: “I think I will do another series. We are talking about it now. But there are a couple of things that need to be ironed out.

“One of the things I said I need to know is who the other coaches are, because I don’t want to be sitting there with somebody I don’t admire or particularly like... there are a few of them!”

Fellow coaches will.i.am and Danny O’Donoghue are expected to return for a second series.
