Jessie J is reported to have signed up for a second series of The Voice in a deal said to be worth around £500,000, following speculation over whether any of the four judges would return to the show.

A BBC source told the Daily Star Sunday that the Price Tag singer – whose act Vince Kidd finished fourth in the final – would ‘definitely’ be back for another series and was very keen to return.

“She did find some of it tougher than expected,” the insider said, “but the positives outweighed the negatives so she’s chosen to come back.

“Now she knows what to expect Jessie is determined to enjoy it more next year, so she’s already excited about getting started.”

There has been a question mark over whether any of the coaches – who also included Danny O’Donoghue, Will.i.am and Tom Jones – would return for a second series after viewing figures for the first proved disappointing.

Although it started off strongly, beating Britain’s Got Talent in the ratings for three weeks in a row, audiences dropped sharply once the ‘blind’ auditions stage ended and the live shows began.

And the series winner, Leanne Mitchell, failed to set the top 40 alight with her debut single Run To You, which only reached number 45 in last weekend’s singles chart.

There has also been talk of several dates on the show’s live tour being shelves following disappointing ticket sales.

However the BBC has said they are pleased with the show, adding that it scored average ratings of 9.2m across the series.

An industry expert said next year would be ‘crunch time’ for the show, given that the BBC signed a £22m deal to produce two series of the show.

“They were always going to get a second run, so this year it was pretty relaxed, even when ratings dipped,” the source said.

“But if next year isn’t successful there’s no way the BBC will be splashing out another £22million.”

Fellow judge Danny O’Donoghue has also indicated he would be keen to return for a second series if asked.
