Sam Smith, Liam Payne and Camila Cabello have all joined the line-up for BBC Music’s The Biggest Weekend.
Also joining the bill are Neneh Cherry, Father John Misty, Stereophonics, Emeli Sande, Rita Ora, Squeeze, 30 Seconds To Mars and George Ezra – as well as dancers from Strictly Come Dancing with the BBC Concert Orchestra.
The Biggest Weekend, which will have concerts hosted by BBC Radio 1, 1Xtra and Asian Network, BBC Radio 2, BBC Radio 3 and BBC Radio 6 Music, will take place in Belfast, Coventry, Perth and Swansea over the May bank holiday weekend, from May 25-28.
Payne, who will perform in Wales, as will Cabello, said: “I am so excited to be playing at The Biggest Weekend – looks like it’s going to be amazing. And I’m so glad to be appearing on such a strong bill – I can’t wait to come back to Swansea!”
Liam Gallagher has previously been announced as a headliner for the event, where his estranged brother Noel will also be playing.
It is the first time the former Oasis rockers have been on the same festival bill at the same time, although the event – which takes place across England, Wales, Northern Ireland and Scotland – will see Noel headline in Perth on May 26 with his High Flying Birds, while Liam will headline in Coventry on May 27.
Other confirmed performers include Ed Sheeran, Taylor Swift, Manic Street Preachers, Snow Patrol and Beck.
More than 175,000 tickets will be available to the public, and it is being billed as the BBC’s biggest ever celebration of music across TV, radio, online and mobile.
The festival will be aired on BBC One, BBC Two and BBC Four – and will also be available to watch on iPlayer, on mobile and online.
