Singer Susan Boyle confronted a group of teenagers who had been taunting her as she travelled in a train from Edinburgh.

The Scottish singing sensation, who shot to fame after her stint on reality show 'Britain's Got Talent', was travelling alone Sunday from Edinburgh to her home town of Blackburn, West Lothian.

Contactmusic.com reports that Boyle, who mouthed 'f**k off' at someone who took her photograph, reportedly defended herself. 'I'm ashamed of you all. Shut up. I don't normally get angry. It's not funny. If it was you, you wouldn't like it.'

An onlooker who witnessed the row praised the way 49-year-old Susan conducted herself during the 30-minute journey.

'Susan was minding her own business on the train. Some people were taking pictures. There were people laughing at her - it was not nice. People noticed she was sobbing. Something was upsetting her,' said the onlooker.

'She then turned to the people sitting opposite her and confronted them. Susan certainly put them in their place. It can't be easy dealing with the fame she has, but she handled it well.'
