The 'I Will Never Let You Down' singer gushed that she's beyond thrilled to be joining Sir Tom Jones, will.i.am and Ricky Wilson on the coaching panel when the BBC One talent series returns in January 2015.
Rita 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!!!!"
She's certainly excited!
Rita's soon-to-be fellow coaches are also looking forward to welcoming her to their family, as she replaces outgoing female coach Kylie Minogue.
will.i.am said: "Season four of The Voice is going to be amazing! (Sir) 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."
Sir Tom added: "I'm really looking forward to coming back to The Voice for season four. 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!"
And Kaiser Chiefs' Ricky concluded: "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."
Rita will join the coaches in Salford next month to begin her new job, as blind auditions for the fourth series kick off. It returns to screens in January next year.
Fans will be pleased to know that co-hosts Emma Willis and Marvin Humes are also returning.
Fresh from presenting Big Brother and Celebrity Big Brother, busy Emma said: "I am delighted to be returning to The Voice for Series four. 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!"
Meanwhile, ex-JLS star Marvin said: "I can't wait for series four. I had such a great time filming the last series and the level of talent was mind blowing, so I can't wait to get started again."
Series three of The Voice UK averaged 8.2 million viewers on BBC One.
