Kathleen Jenkins has revealed the full extent of her nerves as she auditioned for the Britain’s Got Talent judges on Saturday night.

The part-time cleaner, 25, from Newport, south Wales, told What’s on TV: “I was walking out [onto the stage] and I was shaking all over – I can remember actually hearing in my own head: ‘Please stop shaking, please stop shaking, come on, you need to stop shaking because they’re gonna look at you and go what’s wrong?’

“By the time I got halfway through the song I started to calm down a bit. But then afterwards I was shaking again because it was just amazing – it’s so worrying because you don’t know what any of the judges will say, especially Simon.”

Kathleen needn’t have worried though, as the audience and all four judges – Simon Cowell, Alesha Dixon, Amanda Holden and David Walliams – were blown away by her emotional rendition of The Rolling Stones’ Wild Horses.

“Simon’s always the hardest one [to impress] because if he likes you, he likes you, but if he doesn’t like you, then that’s it, so he was the one I was most nervous of meeting. I wanted to impress them all – but he’s the one you need to try a bit harder with.”

When asked why she’d decided to audition for Britain’s Got Talent rather than Simon’s other show, The X Factor, Kathleen said: “One of the reasons for me is that I’d love to sing for The Queen. It’s such a privilege and it’s not something that people get the opportunity to do every day.

“The other reason I entered [BGT] is that I’d like to have a career in singing… and I’d like to move out of my mum and dad’s house!”

Britain’s Got Talent continues on Saturdays at 8pm on ITV.
