"Don't Judge a Book By It's Cover"

Meet the frumpy, unemployed, 47-year-old woman who shocked Simon Cowell.

During auditions for "Britain's Got Talent"  last week, 

Susan Boyle walked on to the stage to snickers from the audience and an eye-roll from Cowell.  After she unleashed a perfect rendition of "I Dreamed a Dream" from the musical "Les Miserables," she left with the crowd on its feet.

"Without a doubt, that is the biggest surprise I've had in three years of the show," said one of Cowell's co-judges, Piers Morgan.

Boyle received three "yeses" from the judges and is the early favorite to win on the hit reality TV series.

"I knew the minute you walked out on that stage that we were going to hear something extraordinary and I was right," said Cowell.
