Susan Boyle became light headed and had to take a seat when she was told that she would meet Pope Benedict XVI in person.
Boyle is set to perform for the Pope at his open air mass in Glasgow but she clearly hadn't realize that she would get a chance to meet the man in face to face. Before she had been told the news she had completed her dress rehearsal at the Bellhouston Park where 65,000 members of the public are expected.
When she had recovered from the shock she said "It's fantastic. The icing on the cake."
She plans to sing the hymn "How Great Thou Art" as well as her signature song "I Dreamed a Dream".
