Amanda has been involved in Britain’s Got Talent ever since the ITV programme began over a decade ago, and has become synonymous with the reality competition alongside music mogul Simon Cowell. Giving her own personal brand of comedy and input about the varied contestants, Amanda has become a favourite on the panel. Yet tonight the judge made a surprising move when she got up on stage at the request of one hopeful - 34-year-old magician and entertainer Graeme Mathews. Amanda was open to whatever tricks and comedy the hopeful was set to throw at her, but there was one moment the actress nearly put her foot down.

Graeme Mathews The act had pretended his plastic cup magically emptied when in fact he had sneakily drunk it, so his insistence wasn’t instilling much hope. “Trust me Amanda I’m a magician!” he declared with a cheeky grin. “No,” Amanda responded uneasily, and Simon could be seen sporting a similar expression. “It still feels heavy, no!” Amanda cried once more, but Graeme ordered her to do his bidding. “Three, two, one…” he began, and Amanda threw caution to the wind.
