Let's Sing and Dance for Comic Relief 2017 is back tonight, and here's the list of confirmed celebrities taking part in the second heat this evening.
Fronted by Mel Giedroyc and Sue Perkins, the showdown returns this evening on BBC One with the second of three star-studded Saturday night heats culminating in a grand final on the 25 March.
Each week, us viewers at home will get the chance to vote for their favourite act who will gain a place in the final.
Once again celebrities will don more fantastic outfits and learn more iconic dance routines for Comic Relief, but this time the brave celebrities will be facing double the challenge – dancing and singing!
The performing celebs will be judged each week by a panel of top TV personalities - this week it's Claudia Winkleman, Adil Ray as ‘Citizen Khan’ and Russell Kane.
But it'll be viewers who decide the top performers. The one celeb with the most votes will go through to the final while the judges will choose who else will make the final from the two runners up in the public poll.
So which celebs are on Let's Dance this year? Here's the line up - and songs - from tonight's second heat.
