Jessie J to leave BBC's The Voice

Jessie J said she hoped she could still be involved with series three

Singer Jessie J has announced she is to leave BBC One's The Voice after serving as a coach for two series.

The 25-year-old made the announcement on Twitter saying she wanted to concentrate on promoting her new album and touring around the world.

"I've absolutely loved my time on The Voice, and I hope everyone saw and knows how passionately I felt about the show," she said.

The BBC said it would begin the search to replace her for the third series.

The singer had postponed a major tour earlier this year as she had been unable to finish her second album in time for the gigs.

"I can't wait to promote my new record around the world and that has to take priority," Jessie J said.

"I shall be keeping a very close eye on series three, showing my support in every way I can, and really hope that in some way that I can be part of the show."

Mark Linsey, BBC controller of entertainment commissioning, said: "We're so sorry to see Jessie go as she's been an exceptional coach on - and advocate for - The Voice, but we totally support her decision to leave due to touring commitments overseas.

It is not yet known if the other coaches, Sir Tom Jones, Danny O'Donoghue and will.i.am will return

"We very much hope that Jessie will remain part of the show and come back and perform for us next series.

"In the meantime, we will now start the search for a new coach."

It is not yet known if The Voice's other coaches - will.i.am, Sir Tom Jones and Danny O'Donoghue - will return to the show next year.

Previously, all four coaches had said they would only reprise their roles if if they could continue doing it together.

Audience ratings for the second series of The Voice failed to match those of the first run last year.

The show was also criticised after series one winner, Leanne Mitchell, sold fewer than 1,000 copies of her debut album during its first week on sale.

Last month saw Andrea Begley crowned winner in the final of the second series.
