Amy Winehouse punched a fan during her concert Saturday night, June 28th, at the Glastonbury Festival.

According to the festival boss the crazed fan had grabbed Amy’s breast prior to her attack.  In addition to attacking a fan, Amy spit her gum into the audience and called Kayne West a c**t at last night’s performance.  Check out the clip of Amy’s attack below.

With all of her anger and drug issues I am surprised that she is still able to land a gig.   I just can’t believe that anyone would still want to see her perform.
