The son of Belfast football legend George Best is set to transform into Prince Charming.
Despite never having sung in public before, Calum Best is in rehearsals for his first ever pantomime.
The 34-year-old will be performing at the Epstein Theatre in Liverpool from next week.
Calum said his biggest worry was those first few seconds.
"It's about getting that first little bit out, you know? But I've said, 'Can we have as many duets as possible, so it's not all the pressure on me'?" he said.
His co-stars include Any Dream Will Do's Chris Barton as Dandini, Beryl Marsden as the Fairy Godmother and Alison Crawford as Prince Charming's love interest, Cinderella.
