Just weeks after returning from a sober stint in St. Lucia, Amy Winehouse emerged from a London pub Monday night with stains on her shirt and what appears to be white powder around her nose.


Winehouse struggled to get from the pub into a waiting car, where she then appeared to pass out in the back seat.

Amy had returned from a long vacation in the Caribbean in July -- and her parents claimed she had finally beaten her drug habit for good.
