London, Oct 26 (ANI): Troubled English singer Amy Winehouse was spotted giggling vacantly in a taxi as she was whisked off on her way to rehab on October 25.

Winehouse, 25, who was looking glassy-eyed and wearing a Hilda Odgen-style head- scarf, was driven off cackling and grinning through stained teeth to her latest London clinic, News of the World reported.

The Rehab singer was assisted by her American pal Blake Wood into getting into the cab, which then took her away as she rolled around in the back.

She was then safely hidden in an exclusive Harley Street clinic, with her dad Mitch saying she was suffering from a chest infection.

Winehouse had a few days earlier been asked by the Metropolitan Police to attend an interrogation, but she never turned up for it, and now with the new developments she has earned herself their anger. (ANI)
