Several British media outlets - including Sky News, Times Online and the Press Association news agency - reported that the woman was Winehouse. Police would not confirm the reports.
Winehouse, 24, recently canceled all concerts and public appearances for the rest of the year on doctor's orders. Her husband, Blake Fielder-Civil, was ordered held in custody in London last month on charges of perverting the course of justice stemming from a case in which he is accused of assaulting a male bartender in June.
Fielder-Civil allegedly tried to interfere with a witness' testimony, according to court documents.
Winehouse, an admitted marijuana smoker, has been dogged by reports of continued drug use amid a flurry of canceled concert dates. She was recently spotted walking outside of her London home wearing a bra and jeans, with no shoes, looking distressed.
