One of our very oldest Christmas Day traditions has to be watching Top Of The Pops - and this year we're going to be treated not only on 25 December, but also on New Year's Eve before we go out boozing. Did we say boozing? We meant, erm, settling down to some knitting. This year all the hottest artists and bands of 2009 have taken part, and we can now bring you some very exciting photos of the acts you can expect to see. JLS will be leaping and pouting their way through your Christmas afternoon, as will Diversity and the all-new Sugababes. We had to give a special mention to La Roux, mostly because she's wearing the most festive outfit of all. Look, that's an actual tiny Christmas tree on her head. Amazing! Also appearing on Christmas Day will be Kasabian, Florence And The Machine, Alexandra Burke, Lily Allen and Muse. We'll bring you details of the New Year's Eve show later this week, but for now have a look through the gallery and tell us which acts you'll be dancing round your tree to?
