“I felt under the weather all last week but didn’t want to miss out on the fireworks display. On Thursday I saw the doctor and was given antibiotics and the following day was diagnosed with Laryngitis by a Harley Street specialist. Up until Saturday afternoon, I was still hoping and praying that I would be well enough to perform but the producers spoke to the doctor who made it clear that I could risk long-term damage to my voice. I was absolutely devastated to be told I couldn’t perform on Saturday night and disappointed not to be able to meet Mariah Carey. I am due to see the doctor again on Friday so fingers crossed I will be able to take part in this Saturday’s show.”
