London's O2 Arena will come alive with some of the biggest acts in pop for Capital FM's Jingle Bell Ball 2015. Kicking off this weekend (Saturday 5 December), the two-day event will celebrate the best in music over the last 12 months in front of a sold-out audience.

It will be a jam-packed weekend with 16,000 tickets having sold out in record time as fans raced to see the likes of Justin Bieber, Little Mix, Jess Glynne and Jason Derulo ring in Christmas. The radio station has struck gold yet again with the line-up following on from the 2014 event, which saw the likes of Taylor Swift, Sam Smith, Ella Henderson and 5 Seconds Of Summer hitting the stage.

Ticket-holders will be disappointed with the news that US pop star Ariana Grande has pulled out of her performance after cancelling all scheduled international tour dates in December. Announcing the news, Grande told her Twitter followers: "Babies, I'm so sad I won't be able to make it abroad this December but I can't wait to see u & reschedule for next year.i love you so much."

Still, it looks set to be a fun weekend so the IBTimes UK rounds up everything you need to know about this year's Jingle Bell Ball...
