The 47 year old, who lives alone with her cat Pebbles in one of Scotland's poorest regions, will now perform in a live show on Sunday, weeks after her surprising performance of I Dreamed a Dream" from the musical Les Miserables" shocked judges and charmed tens of millions of people worldwide.
Boyle's performance last month on the American Idol"-style show Britain's Got Talent" has been viewed almost 60 million times on You Tube, and saw the shy Scot feted by celebrities, including Oprah Winfrey and Demi Moore.
The awkward looking Boyle, who says she's never been kissed, was greeted with giggles from a skeptical audience and eye rolls from the show's famously sardonic judge Simon Cowell when she appeared in April but startled viewers with her soaring voice.
In an update on her Twitter Web site, Moore wrote that Boyle's voice had made me teary!"
Cowell and his fellow judges said Saturday that Boyle is among 40 performers they've selected to advance in the competition.
