On Air Now
Will Manning and Aimee Vivian 4pm - 7pm
They're already one of the most talked about bands around and they haven't even released a single yet. Fresh from supporting Lemar on his UK tour, we can now officially announce that JLS have signed up to appear at the Summertime Ball.
You watched them on the X Factor, now prepare to experience the boys in the flesh.
Aston, Marvin, Jonathon and Oritsé will no doubt set pulses racing when they take to the stage at the Emirates Stadium, performing the songs which made them famous on the show, as well as treating us to a preview of what's to come from their hugely anticipated debut album, which is due later this year.
Guaranteed to be a real highlight of the show, JLS are not to be missed.
