Mel Giedroyc and Sue Perkins are set to get "intimate" as as they host Let's Sing and Dance for Comic Relief 2017.
The new series starts tonight on BBC One and they're going all out to entertain.
Mel teased: "It will be ruddy mayhem is what it will be. It will be such a laugh. I don’t feel nervous about it - I just can’t quite believe we’re about to do it and it’s going to happen and be seen. But we often feel like that with the stuff we do."
Sue joked: "I’m hoping we get fired out of a giant cannon!"
She revealed: "There’s a possibility that Mel might be doing an intimate lift, that’s all I’m going to say. If it goes wrong it could be an extremely intimate lift."
Mel added: "It will be! I can’t wait!"
Let's Sing and Dance will see celebs performing as famous music stars, so who would Mel and Sue channel if they were a part of the all star cast of contestants?
Mel suggested: "So we’ve done (Elaine) Paige and (Barbara) Dixon for Stars In Their Eyes which obviously doesn’t involve much dancing."
Sue continued: "We sang I Know Him So Well - we couldn’t look at each other when we were doing it and became too hysterical. The choreography was us crossing this checker board, but as soon as I caught a whiff of Mel dressed as Elaine Paige, the bladder went quite significantly."
She joked: "I looked like a Portuguese Water Dog."
Mel spilled: "We got into real trouble because the dress rehearsal, which was supposed to take about 20 minutes because there were five acts on, we were laughing so much that everyone was really annoyed with us - it took over an hour. And we still came second to last."
Let's Sing and Dance for Comic Relief airs tonight on BBC One.
