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

     Simon Cowell, one of the judges of the talent show spoke of his shock over Ms Boyle's voice. "This     lady camp 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 to Dream from Les Miserables. She knew we were going to  have that reaction and just to see that look of satisfaction on her face through -it was one of my favorite    moments," Cowell said.

     The performance was posted on line 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 hasn't thought of changing her                  appearance. She said that her friend helped her with make-up. "I mean, that's hardly a makeover," she      added. Ms Boyle also spoke of the reason she first began to explore her vocal talents, "I was kind of slow at school, so getting like singing was a good way of hiding behind that and thus it built my confidence.
