The Price Tag singer tweeted: "I WILL be a coach on the 2nd series of The Voice UK! I'm B B B BACK! As I have always said. Unless you hear it from me- Don't always believe what you read! Can't wait! #thevoiceuk #weback *fist to the sky* ;)"
The Laserlight hitmaker was referring to reports published in the press, suggesting that she had infuriated executives of the BBC talent contest by turning up late for recordings and with her negative comments made during a recording of The Graham Norton Show.
Jessie, who recently performed at the Olympics closing ceremony with Queen, is the first judge on The Voice UK to officially confirm her return, although both Tom Jones and The Script's Danny O'Donoghue have said they would love to come back for more spinning-chair action.
Will.i.am, also a coach on The Voice when it launched earlier this year, has recently teamed up with Danny for The Script's latest single. Proving that their on-screen disagreements are nothing but creative differences, the pair release their new tune, Hall Of Fame, on 2 September.
