Fresh from her hospital stay, Amy Winehouse headed to the Glastonbury Festival to perform for the 80,000 attendees, when a face in the crowd reportedly rubbed her the wrong way.

According to the Associated Press, after singing her hour-long set, Amy climbed off stage and threw a punch at a fan! Witnesses say that the singer was provoked, as the fan had tried to grab Amy, but still, isn't that what fans do? Don't they try and touch the people on stage?

In other Wino news, the singer made it to the concert honoring Nelson Mandela's 90th birthday earlier in the weekend and managed not to hit anyone there. Amy reportedly sounded good during her performance, and she honored her man, "Blaaaaaake Incarcerated", by wearing his name in a heart in her hair.

Yup. His name. In a heart. In her hair. Like I said -- hours upon hours of entertainment.
