The first soundchecks have begun at the O2 Arena today ready for the final night of Capital FM's festive concert.
Emeli Sande and The Saturdays are both ready to take to the O2 Arena stage tonight after completing soundchecks for the Capital FM Jingle Bell Ball.
The 'Heaven' singer is due to perform at the sold-out venue this evening on a bill alongside the likes of Jessie J, JLS, One Direction, Ed Sheeran and Wretch 32.
Five-piece girl band The Saturdays will also make an appearance fresh from their 'All Fired Up' arena tour, and will sing a variety of tracks from across their three studio albums.
All five girls, including expectant mother Una Healy, prepared for tonight's event with a rehearsal of 'On Your Radar' single 'Notorious'.
The Jingle Bell Ball 2011 kicked off yesterday (3rd December) with performances from Rihanna, Calvin Harris, Olly Murs, The Wanted, Labrinth, Rizzle Kicks, Pixie Lott and Jason Derulo.
