BGT Charlotte's Red Or Black slip

Britain's Got Talent singer Charlotte Jaconelli has revealed she fell off the stage during rehearsals for her Red Or Black appearance.

The soprano and tenor singing sidekick Jonathan Antoine are set to perform The Prayer with Welsh male choir Only Boys Aloud on the next episode of the ITV1 show.

"It was really great to get up and perform on Red Or Black after appearing on Britain's Got Talent. Apart from when I fell off the podium in rehearsal when the pyros went off," admitted Charlotte.

"I'm scared of fireworks and I ducked for cover, lost my balance and hit the stage floor when the pyros went off. I'm not sure whether people thought they should help me or just laugh. I was hysterically laughing!"

Jonathan revealed that he enjoyed having his own motor home for the show, which airs on September 22.

"I had my own personal Winnebago - my Dad was more excited than I was - he was having a proper exploration," he said.

Charlotte added: "That was the coolest thing! I remember thinking, 'Wow we've made it'. We felt like Hollywood stars."

The singing pair, who came second to dancing dog act Ashleigh and Pudsey, are set to release their debut album Together on September 24.
