Susan Boyle: Demi Moore switches favourites in Britain's Got Talent
Jamie Pugh looks set to be a big hit in America, just like rival contestant Susan Boyle, after Britain's Got Talent's best-known fan backed him.
Hollywood star Demi Moore, 46, posted his performance on Twitter, with the message: "So moving.
Teary again, wow!" In another message she called him "amazing".
Within an hour, tens of thousands of people had watched Jamie's audition online. A similar thing happened when Demi posted a video of Susan Boyle on her site.
