After wowing the judges (including the ever-cranky Simon Cowell) on Britain's Got Talent, Scottish singer Susan Boyle has become a YouTube Internet sensation and garnered international praise overnight.

The 47-year-old appeared on the CBS's Early Show Thursday to reprise her Talent performance of "I Dreamed a Dream" from the musical Les Miserables. Boyle's gorgeous a capella delivery earned praise from Broadway's Patti LuPone, who first introduced the song in 1985.

"Susan," said LuPone as she called into the Early Show, "you've got pluck, girl."

As of Thursday morning, the online video clip of Boyle's performance had been viewed more than 11 million times.
