When we talk about stars, especially women stars, it seems that they are always young, pretty and own attractive body shapes. But recently a Britain’s Got Talent(英国达人) star Susan Boyle has changed our views completely.

Simon Cowell, one of the organizers of the talent show spoke of his surprise over Ms Boyle’s voice. “This lady came up, and I’m thinking, ‘This will take five seconds and I can go to have a cup of tea.’ That changed when she began to sing I Dreamed a Dream from Lea Miserables. She knew we were going to have that reaction(反应) and just to see that look of satisfaction on her face midway through — it was one of my favorite moments,” Cowell said.

The performance was posted online and before long, the 47-year-old Scottish woman has been famous all over the world.

Speaking from her home in Scotland, Ms Boyle said that she hadn’t thought of changing her appearance. She said that her friend helped her with make-up. “I mean, it’s meaningless.” She added.

Ms. Boyle also spoke of the reason she first began to explore her musical talents. “ I was kind of slow at school, so getting something like singing was a good way of hiding behind that and therefore it built my confidence.’’
