The girl is tough, that's for sure. Just after being hospitalized for major health issues, singer Amy Winehouse performed at a special birthday concert for Nelson Mandela and then last night, sang for one hour on stage in front of a crowd of 80,000 at the Glastonbury music festival. She even had enough in her to partake in a little altercation with a reveler from the crowd. It's reported that the fan tried to grab Winehouse, and she fought back.

As for Winehouse's health problems, her father says she has emphysema from smoking cigarettes and crack cocaine. Her spokeswomen says she only has pre-emphysema symptoms. Whatever the case, her diagnosis isn't slowing her from performing -- or smoking. Just after her hospital release, she was seen smoking a cigarette.
