Join Capital as we give you an exclusive insight into everything that's taking place at the O2 Arena in London.
Capital FM's Jingle Bell Ball is preparing to get underway and preperations have been taking place for a long time.
The final bits of the stage are being put together, the last remaining lights are being tested and the catering team is cooking up a storm in the kitchen.
But just how much goes into putting on one of the biggest events of the year?
Well, there will be a total of 190 loud speakers being used to give fans the best chance to hear every syllable from their favourite artist's biggest hits.
There is 25 tonnes of audio equipment in place with 40 sound engineers meticulously checking over every inch of it to get it ready for the big show.
Also, did you know that it would take a total of 3.8 million pints of beer to fill the arena and the Eiffel Tower could fit inside the building on its side?
Today (8th December) will be the first of two nights inside the O2 Arena in London with the likes of One Direction, Bruno Mars, Cheryl Cole, JLS, Lawson, Rizzle Kicks Little Mix and The Script all performing.
Tomorrow will see Girls Aloud starting proceedings with The Wanted, Conor Maynard, Example, Rita Ora, Calvin Harris and Pink all on the line-up.
