Ariana Grande and Jess Glynne join Jingle Bell Ball line-up
Ariana Grande, Jess Glynne and Jason Derulo have been announced as performers on night one of Capital's Jingle Bell Ball.
The pop stars will also be joined by David Guetta, Nathan Sykes and Years & Years on Saturday December 5 at London's 02 Arena.
Little Mix have already been confirmed as the first act for night two on the Sunday, with more acts set to be announced on Thursday from 7am.
Grande was a guest on Wednesday's Capital breakfast show with Dave Berry and Lisa Snowdon, where she announced she would be jetting in to London for the concert. The singer, 22, will perform a set including her new single, Focus.
Glynne, who is the second British female artist ever to have five number one singles in the UK, is also confirmed to perform - alongside singer-songwriter and former Wanted member Sykes, and electronic dance hit-maker Guetta.
Singer-songwriter Derulo's appearance was announced on Monday. Years & Years, who in 2015 released their debut single King, are also set to appear at the Ball.
The Jingle Bell Ball is now in its eighth year. Last year's acts included Taylor Swift, Sam Smith, Ed Sheeran, Take That, 5 Seconds of Summer and Jessie J.
