The 'Britain's Got Talent' judge will take on the role of Prince Charming in the Sky One original comedy, alongside 'Car Share' star Sian as the titular character, as well as British acting legends Celia Imrie and Sir Tom Courtenay.

David - whose production company King Bert Productions are behind the show - said: "When you read a story to a child and it ends 'they lived happily ever after' the child often asks what happened next?

"Now, for the first time in history, we will reveal what happened next for Cinderella, Prince Charming and the Wicked Stepmother.

"What happened, 'After Ever After?'

"We have assembled a magnificent cast and crew for this one-off family comedy film. It promises to be a real treat for TV viewers this Christmas. I want to say a huge thank you to Sky for making it possible."

The comedy will begin where the famous fairy tale left off with Cinderella having just married Prince Charming.

However, all is not as good as it seems for Cinders due to her image-obsessed, floss-dancing hubby.

The festive show will see Cinderella trying to save The King (Tom) from her evil stepmother Madame Blackheart (Celia) and her calculated stepsisters Dumbella and Rubella.

Jo Sargent, executive producer of King Bert Productions, said: "We are delighted to bring this reincarnation of a classic fairy-tale to life for Sky One at Christmas and to finally answer the question that children have pestered their parents with for generations, 'But what happened after ever after?'
