"Train wreck" may not even do justice to this woman.

Her producer said yesterday that she's "not ready to work." Now we know why. Well we already knew why, but here's some photo evidence.

Amy Winehouse was, shall we say, um, a little dressed down last weekend while enjoying a U.K. holiday with friends. Check out these pics:

The trials and tribulations of Amy Winehouse continue.

Dressed only in a black bra and tiny denim shorts, Winehouse - sans beehive - revealed a bald patch and her efforts with an at-home hair dye kit on her bangs. At least we don't believe she head-butted anybody.

"It's Amy enjoying the sun at the weekend," her London rep said.

A friend agrees, saying the Amy Winehouse photos just show a girl taking advantage of the good weather in her own style. Whatever that means!

"The sun makes people do crazy things," a Winehouse pal said. "Walking around in your bra in your own garden when it's hot out isn't all that crazy. She doesn't care about having her picture taken like that. She wouldn't even think about that. It's Amy being Amy. She doesn't care what people think."
