London's O2 Arena will be treated to a festive makeover this weekend as Capital FM's Jingle Bell Ball returns for another year. Hosted across two days, a host of pop's biggest acts will grace the main stage armed with some of the hottest songs of the last year.

This year certainly has big shoes to follow as the 2015 Jingle Bell Ball welcomed 30,000 music fans to the O2 Arena and enjoyed stellar sets from the likes of Taylor Swift, Justin Bieber, Ed Sheeran and David Guetta.

Sharing the radio station's anticipation for 2016's event, Ashley Tabor, founder of Global Radio and managing editor of Capital FM, said: "This year's line-up just keeps getting bigger... The world's hottest girl band [Little Mix] will be taking to the stage to join an already massive line-up for the first night of Capital's Jingle Bell Ball.

"The girls always put on an amazing show and we know they'll electrify the O2 Arena for Capital listeners when they take to the stage. I can't wait for Saturday 3 December – it's going to be one incredible night!

Before you begin trekking off to the arena, get clued up on all this important information you'll need for what will be a fun and – most importantly – festive weekend.
