The unlikely duo have been announced as judges on the Saturday night series, which will see rival musical groups facing-off against each other.
In a statement, Kelis said: “It’s kind of nice when things come full circle. I started singing in the choir as a child so it’s always been something special to me. Now here I am 20 years later as a judge on ‘Pitch Battle’.”
Mel added: “I am soooo excited to be presenting this new show and ‘PB’ will definitely be bringing some cracking music into people’s living rooms every Saturday!
“Not only are we going to be joined by some brilliant groups and megastar judges each week but to top it all off my old mucker the original twisted choir starter Gareth Malone will be there too. What a combo!”
Details of ‘Pitch Battle’ were announced earlier this year - just as ITV launched its version of ‘The Voice’, after the broadcaster poached the rights to air the show from the BBC, in a multi-million pound deal.
Billed as “a contemporary competition that will feature the best singing groups from across the UK and from all musical styles: pop, rock, folk and gospel to a capella groups and even fishermen’s choirs”, each act will go head-to-head in five hour-long heat episodes, as they compete in a series of choral challenges. These include Riff Offs, a soloists challenge and an acapella round.
The successful groups who make it through to the heats, will battle it out in the live final.
The six part series will debut this summer on BBC One.
