Amy Winehouse has been busted for alleged drug possession in East London………………again.

She was questioned by police and is apparently cooperating with ongoing investigations.

The must-go-to-rehab-again Winehouse handed over a video showing the singer doing drugs.

Last month she was warned about "common assault".

Despite her assertion she'll be recording the theme for the Bond film, reps for 007 stated matter-of-factly Winehouse "was not ready to record"…..anything, anytime soon.
