EastEnders star Danny will be cheering his onscreen wife when she takes to the dancefloor and has jokingly told Craig that he better not be too harsh in his critique.
He told Daily Star Sunday: "I'll be there for the first show, of course. I'm rooting for Kellie. She's my screen wife and I love her dearly. If Craig is nasty to Kellie, then I am going to iron him out. I'm very protective of her so we will see how it goes."
Danny plays Mick Carter in EastEnders, while Kellie stars as his wife Linda.
Kellie has been partnered with Kevin Clifton this year.
In a recent video of them rehearsing, Kellie said: "I'm feeling really good. I think I have a basic understanding of the main bulk of the dance. Which is good… But I'm really tired. I'm really, really tired. I can't believe how tired I am after just one day. It's quite scary."
"Kellie's made such a great start to training. I'm really enjoying dancing with her. She's very enthusiastic and she is really open to throw herself in and try anything I throw at her."
