After being hospitalized for Emphysema, Amy Winehouse surprised her fans with a performance at Nelson Mandela's 90th B-day this past week-end.
She looked healthy and her voice sounded good.
Amy was wearing a white-and-black form-fitting dress, had her beehive as high as can be with an accessory dedicated to her Blake Incarcerated! She sang "Rehab" and her massive hit "Valerie" for the crowds.

On Saturday though, Amy took to the stage with a rage!
She was performing at the Glastonbury Festival in Somerset, England when she suddenly stepped down the stage and punched a fan!

It's not clear what sparked this behavior, but reports are that the fan tried to grab Amy.

Despite all this, she did perform well and sounded very good and looked very healthy.
She performed for an hour and sang some of her most popular songs like "You Know I'm No Good" and "Rehab", in addition to another song, she wrote for Blake called "Wake Up Alone".
