June 26 (UPI) -- Teenagers attacked singer Susan Boyle with rocks and insults on separate occasions as she rode a bus in her Scottish hometown.
"We were inside the bus and they were throwing stones, screaming and shouting things," one witness said. "Another time 10-15 of them were surrounding and throwing stuff. They lit a piece of paper and threw it at her face."
But the rowdy kids didn't stop there.
"Then I was going inside the Mill Centre, Susan was walking out and they were all standing at the entrance and they said to her 'why don't you get yourself a pair of glasses you ugly, old [expletive] It's horrendous," the witness added.
"This disgusts me. Vile little vermin," tweeted former CNN anchor Piers Morgan.
Boyle, 56, came to fame during an appearance on Britain's Got Talent in a 2009 video that went viral, becoming one of the most-watched clips on the internet. Since then, Boyle has put out albums and done tours, but has chosen to remain in her hometown Blackburn, West Lothian.
