Amy Winehouse Elbows and Punches Fan

In the midst of performing an hour-long set, Amy Winehouse allegedly punched a concert-goer at the Glastonbury Festival in Somerset, England on Saturday.

Witnesses say that a fan tried to grab the singer, though it is unclear what provoked the altercation.

Despite the scuffle, Winehouse was reportedly in fine voice. She was even coherent enough to give her jail-bird husband--Blake Fielder-Civil-- a shout out.

"I wrote this one for Blake," she told the crowd before singing "Wake Up Alone." I thought I'd never see him again."

"I've only got two weeks left of this predicament, so this one's for you, Blake," she mumbled.

"I looooove youuuuu Blaaaaaake," she probably also cooed.

To all of which I say, "what's the big deal?" You take a wild animal out of her natural habitat, and expect her to act normal?!?!

Now who's the crazy crackhead?

Just be glad Winehouse made it through her two-song performance for the Nelson Mandela 90th birthday tribute concert in Hyde Park on Friday. Hey, I was nervous. It was touch and go during the days leading up to the event. Supermodel Naomi Campbell was removed from the list of celebrity presenters. And Winehouse missed a photo shoot. It could have been ugly.
