For a gal who supposedly has emphysema, singer Amy Winehouse sure is feisty! The troubled little drug machine was performing at the Glastonbury Music Festival the other day when a fan annoyed her and so she had to lay the smack down. She first threatens the bounder with a very jagged elbow, and then reaches through the crowd with her deadly talons to exact bony justice before being led away by her guards and then nearly collapsing. See it after the jump!
