Looking like she's been doing crystal meth with Britney Spears and Howie Day, a distraught and strung-out Amy Winehouse was spotted wondering the streets of London at 5:45 this morning wearing just her bra, jeans and no shoes.

The Daily Mail (U.K.) reported that Amy Winehouse, who recently canceled all her tour dates, had emerged from a friend's house in East London early this morning looking quite distressed, wandering the streets aimlessly and near tears.

Warning: The celebrity photo below is extremely graphic ...

Amy Winehouse: Sexy as hell... if you're into heroin and meth addicts.

A witness told the Daily Mail, "She came out of the house, walked down the drive and wandered around the pavement for a bit. She looked upset and agitated but there was no obvious reason for her to come outside. It was weird."

Yes, you could say that. A rep for Winehouse offered this explanation, "Amy had been fast asleep and heard a noise. She then went outside to investigate."

Loosely translated, that means, "Amy had called her crack and meth dealer after her supply had run out, then went outside when she thought she heard him."

Any Winehouse is clearly not responding well to the absence of her husband, Blake Fielder-Civil, who was recently jailed and is being held without bond on charges of witness tampering in conjunction with a previous arrest for assault.

On the other hand, we've seen plenty similarly absurd Winehouse photos when he was a free man. One thing's for sure: We'll stay tuned to this train wreck watch.
