Teenage dancer George Sampson has been crowned winner of 2008 Britain's Got Talent.

All three judges stood to clap as smiling Simon Cowell said: "George, let me tell you are the dancing version of Rocky. You deserve everything. You've battled your way to the top. Congratulations."

Holding his head in his hands George said: "I'm speechless... wow! Just thanks so much everybody. You've changed my life I couldn't have asked for anything else."

He wowed the judges with a break-dance routine to Singing in the Rain. The song was a new version but he danced under a shower of water just like Gene Kelly.

Simon said: "On sheer determination you've got to have a chance of winning. I've got to tell you, doing it once is tough, doing it twice with the pressure you're under, is incredible.
