When 47-year-old volunteer Susan Boyle stepped onto the stage of Britain’s Got Talent and announced she was unemployed, had never been married and “never been kissed, actually”, few in the audience would have wondered why. This Ms Boyle, looking unfashionable, from a village in Scotland, shocked the three judges and the audience with the song I dreamed a dream from the musical Les Miserables on a show of Britain’s Got Talent, one of the hottest reality shows in Britain.

She couldn’t hide the awkwardness when walking to the center of the stage in a housedress, and everyone — including the judges — seemed laughing at her when she said she wanted to be as successful as Elaine Paige. As soon as she began singing, however, everyone in the auditorium fell silent, then rose within seconds to applaud her incredible voice as the celebrity judges sat open-mouthed, and remained standing to the end.

After her performance, one of the judges Piers Morgan said, “Without doubt that was the biggest surprise I’ve had in three years of this show. When you stood there everyone was laughing at you. No one is laughing now. That was amazing.” Actress Amanda Holden followed, “I’m so thrilled because I know that we everybody were against you. I honestly think that we were all being very cynical (愤世嫉俗的) and I think that’s the biggest wake up call ever.”

Susan obviously won over the hearts of millions around the world with sensation spreading across the Atlantic. Hollywood actors Ashton Kutcher and Demi Moore — who between them have nearly 1.5 million followers — speak highly of her. Kutcher posted a link to the video clip (片段). The Scottish talent made her live American debut via satellite connection on CBS’s The Early Show, doing an interview and singing live from her room. And she already accepted an invitation from talk show host Oprah Winfrey.

Now Boyle has become one of the world’s hottest celebrities. The video clip of her performance has been viewed more than 50 million times on Youtube, becoming a hit on the Internet.
