(CNN) -- Scotland's Susan Boyle gives new meaning to the term "overnight sensation." The "Britain's Got Talent" contestant was expected to be something of a joke when she first sauntered on stage, but she absolutely wowed the audience, the judges -- and then the world via the Internet -- with her stunning rendition of "I Dreamed a Dream." Along with Simon Cowell and Piers Morgan, Amanda Holden is a judge on "Britain's Got Talent." But like others who stumble upon sudden fame, she found the pressure and scrutiny to be overwhelming. "Talent" judge Amanda Holden and Dr. Drew Pinsky of VH1's "Celebrity Rehab With Dr. Drew" joined CNN's Larry King Tuesday night to discuss Boyle's hospitalization for stress and the toll the spotlight and media criticism might have taken on her mental health. They also discussed whether Boyle will develop the emotional stamina for a high-pressure singing career.
