Ariana Grande and David Guetta are among acts confirmed for Capital's Jingle Bell Ball with Coca-Cola.
The annual two-day event at The O2 in London will feature a jam-packed line-up of stars including the 'Problem' hitmaker and French DJ.
After being announced for the show, Ariana said: "I'm so very excited because I'm a festive person and it's going to be a blast, I'm so excited! I'm going to be the funniest, most festive person you've ever seen!"
Both artists will perform on the first day of the Ball on December 5, where other acts including Years & Years, Jason Derulo, Jess Glynne and Nathan Sykes will also grace the stage.
Former The Wanted singer Nathan said: "I'm very excited to be back, it's always a great venue to play, there's always such a special atmosphere at the Jingle Bell Balls. There's always so many great artists and it always comes with a great fan base as well. Everyone's there to have a really great time, so yeah, I'm really looking forward to it."
The second day will feature a performance from 'Black Magic' singers Little Mix who previously played at the event in 2012 and 2013.
And Perrie said: "We love doing the Jingle Bell Ball, everyone is on top form for a good laugh and a good boogie and it's a good chance to catch up with our other artist friends!"
Tickets to the show go on sale on Friday (06.11.15) at 8am.
