Don´t fuck with Amy Winehouse yo. Just a few days after being let out of hospital where she had suspected tuberculosis and emphysema, Amy was performing at the famous Glastonbury festival in England (think Woodstock, but with more advanced drugs), when a fan attempted to mess with her beehive. Amy reacted violently, lashing out at the fan in an attempted ass kicking.
Of course, odds are that Amy wasn´t really worried about her hair, its just that she keeps her stash inside that beehive, and she wouldn´t want to lose it to some scummy fan. The video below shows the entire incident. First she goes in with the elbow, and in then with the right hook whilst security stands there like a large bag of feminine hygiene product.
