YouTube singing sensation Susan Boyle was noticeably nervous during her semifinal performance on Britain's Got Talent, but that won't keep her from the U.K. talent show's final round.

Boyle, who looked slightly more made up than during her first outing, shook off the jitters to deliver a powerful rendition of "Memory" from the musical CATS. (Watch the full performance below.) Fans at home voted Boyle the best in her semifinal group of eight acts, and the judges put her through to next week's finale. She will sing for the title Saturday.

"Fantastic, absolutely fantastic," Boyle said, as she danced in celebration. "What pressure? I've really enjoyed myself tonight."

The Scotish singer wowed Britain's Got Talent judges and became an Internet viral video sensation after her first performance of "I Dreamed a Dream" from Les Miserables. She has since made appearances on Larry King Live, The Oprah Winfrey Show, and has even been referenced on The Simpsons.

Oddsmaker William Hill has Boyle as the overwhelming to win the show, according to The Associated Press.
Boyle said she wants to win "more than anything ever in my life," and feels that a win will "prove that I am a worthwhile person."
