BBC One's Let's Dance for Comic Relief will be back this year with a singing twist.
And this week the first celebrities on the line up for 2017 have been revealed.
BBC One announced Let’s Sing and Dance for Comic Relief, a spin-off of the original Let's Dance contest, last year.
Let's Dance originally ran for five series as part of the annual Comic and Sport Relief fundraisers until being dropped in 2013.
The comedy talent contest involved celebrities mimicking iconic dance routines. Highlights included Robert Webb's take on 'Flashdance' and Rufus Hound recreating Cheryl's 'Fight For This Love'.
But it'll return in 2017 and this time the celebs will have to dance AND sing.
Mel Giedroyc and Sue Perkins have already been confirmed as hosts of the (sort of) brand new Saturday night prime time show.
The pair will bring their own formidable and comic double act to Let’s Sing and Dance for Comic Relief with access all areas to the performing celebrities’ routines, breath-taking – in more ways than one – vocals.
Let's Dance and Sing celebrities line up
Celebs signed up for the new series include Astrologer Russell Grant, Corrie's Sally Lindsay, comedian Sara Pascoe, actress Harriet Thorpe and the cast of shows including The One Show and Holby City.
Just live past series, there will be a different line up of celebrity guest judges on the panel each week to critique the performances.
Names set to give their views include Jo Brand, Jason Manford, Paul O'grady, Franke Skinner, Jennifer Saunders and Claudia Winkleman.
Let's Sing and Dance will start on BBC One on Saturday nights in March.
