A host of new acts have been added to the already amazing line-up for this year's Capital FM Jingle Bell Ball, which is set to take place on Saturday, December 5 and Sunday, December 6 at London's O2 Arena.

Nick Jonas, Sigma, Justin Bieber, Charlie Puth, Calvin Harris and Ellie Goulding will now join Little Mix for the Sunday night concert. Speaking about being added to the bill, 'Chains' hitmaker Jonas told the station:

“A show this big, you have to bring incredible production and really set the bar high and really go for it. I'm trying to build a great set for the fans there in London and make it a really special night. I'm honoured to be part of the show and bringing in the holidays is always fun and a celebration of what a great year it's been.”

Songstress Ellie Goulding also spoke about being part of the show, adding; “If there is some kind of me storming the stage situation, then maybe. I might have to force it! That could be really cool, I'll ask him and see what he thinks. I've done it quite a few times now and it's genuinely a really fun show, everyone's lovely and it's a good vibe."

Tickets for the event will go on sale to the public at 8am on Friday, November 6.
