In an interview on The Early Show Thursday, Boyle admitted it "hasn't really sunk in yet."
And little did she know that the broadcast would put her in touch with Tony Award winner and Broadway legend Patti LuPone, who first did the hit that made Boyle famous, overnight.
Boyle, 47, shocked viewers, judges and audience members when she performed in a preliminary round of the TV show, "Britain's Got Talent." She sang "I Dreamed a Dream," from the musical "Les Miserables."
When Boyle, a volunteer church worker from Blackburn, Scotland, first stepped on stage, she said, "I'm nearly 48, currently unemployed, but still looking."
But probably not unemployed for much longer, reports CBS News correspondent Mark Phillips.
By Thursday morning, a video clip of Boyle's performance on YouTube had been viewed more than 11 million times.
In her interview with Early Show co-anchors Harry Smith and Maggie Rodriguez, Boyle noted that kids who made fun of her in school are now -- singing her praises!
Boyle said she got the courage and inspiration to perform from her late mother, whom she cared for for many years.
Phillips told her remarkable -- and most unlikely story, then Boyle had her chat with Smith and Rodriguez.
Then came the surprise for Boyle and Early Show viewers: Waiting to talk to her by phone was LuPone, who first sang "I Dreamed A Dream" in 1985, in London's West End.
