Chart-topping singer Rita Ora has been signed up to replace Kylie Minogue as a coach on BBC1 series The Voice.

The Hot Right Now singer, who has had a brief guest stint as a judge on The X Factor panel, joins returning Kaiser Chiefs frontman Ricky Wilson and regulars Will.i.am and Sir Tom Jones.

She will begin filming for her new role in the spinning red chairs at blind auditions next month and will be seen on TV when the fourth series begins in January.

Ora, 23, said: "So excited to be part of, and for my team to win, The Voice this series. Let's have some fun, Will.i.am, Tom and Ricky.

"I'm really looking forward to the blind auditions - and spinning in my big red chair. Excited."

Ora, currently in the charts thanks to her collaboration with Iggy Azalea on Black Widow, will also be seen making her movie debut while The Voice is being aired with the release of Fifty Shades Of Grey in February.

Sir Tom, who is returning for a fourth series, said: "Not only do I get to know and work with Rita, I can once again enjoy hearing and seeing the talent that comes from just about every corner of the UK. I respect and admire all those who have the guts and determination to get through each challenge that the show presents, so let's see what happens in 2015."

Will - also back for a fourth time - said he thought the new series would be "amazing".

"Tom Jones is our rock, Ricky is awesome and it's our pleasure to welcome the very talented Rita Ora. Rita is sweet, spicy and sassy - she's going to be a great addition to the coaches team."

Wilson said: "I enjoyed spending last winter with The Voice - it's definitely fun to be part of a show with a spinning chair. I hope Rita likes it too. I'm sure the audience will love her."

The presenter line-up will remain as Emma Willis and Marvin Humes, after the duo made their debut on the show earlier this year.

Willis said: "It was a privilege to be part of the team who uncovered such amazing talent last year and I loved every minute of it. Bring on those spinning chairs - here's to another cracking series!"

BBC1 controller Charlotte Moore said: "Rita Ora has a unique sense of style and her no-nonsense attitude will really mix things up on the spinning chairs alongside Will.i.am, Sir Tom and Ricky."
