Susan Boyle was a reminder to all of us that we should never judge a book by its cover. The audience - and judge Simon Cowell - laughed when the dowdy-looking woman marched onto the 'Britain's Got Talent' stage in 2009 and announced that she wanted to be a singer. Nobody was laughing by the time she'd finished 'I Dreamed a Dream,' but plenty of people were crying. She absolutely blew everybody watching away with her phenomenal singing voice. She didn't win the talent show, but Cowell signed her anyway.
Boyle didn't cope well with fame. She hated the press attention, and later revealed that she suffered from autism which made things even more difficult for her. Eventually, she stopped answering the phone and applied to work in a local betting store instead. She stayed out of the limelight for several years, but more recently she surprised everyone by turning up on 'America's Got Talent' in January this year. She's back!
