Pudsey Bear is joined by Terry Wogan, Tess Daly, Fearne Cotton, Nick Grimshaw and Zoe Ball to host the evening's entertainment.
The EastEnders cast will be coming at us live from Albert Square for a spectacular dance number. One Direction will also be performing, Call the Midwife are doing a special sketch and Doctor Who are getting in on the action too.
There's also a Dancing-On-Ice-meets-Strictly special with Jane Torvill and Christopher Dean facing off on the dancefloor.
And of course, the reason they're all there is to help the disadvantaged children across Britain, so they'll be asking for donations too.
