'Britain's Got Talent': Jackie Evancho Wows at Finale Following Anonymous Show Fixing Allegations (Video)

Jackie Evancho

Eleven-year-old singer Jackie Evancho wowed 'em at the Britain's Got Talent final Saturday night. The breakout moment may be just what the show needed after anonymous contest fixing allegations against Simon Cowell's production company, which pertained to contestant Ronan Parke, hit the web earlier this past week.

Pint-sized soprano Evancho sang "Nessun Dorma" from Giacomo Puccini's opera Turandot to an overwhelming response. (YouTube has disabled embedding capabilities for the performance but you can see it for yourself here.)

Evancho said it "was an honor" to perform on Talent and she tweeted earlier in the day, "London is amazing and I love the people. They're so nice. Tonight's my big night - my knees are shaking. lol I hope i make it!”

Jai McDowall was crowned the newest winner of Britain's Got Talent on the same night.

Evancho was runner-up on America's Got Talent last year, where she sang a duet with her idol Sarah Brightman on the finale. She later inked a recording contract SYCO/Columbia Records -- the label of Britain's Got Talent standout Susan Boyle -- and her debut effort, O Holy Night, went platinum in Dec. 2010.

Her next album, Dream With Me, will be released on June 14.

Evancho really does sound like an adult when she sings but there always seems to be a disconnect between what she looks like and what she sounds like.
