AMY WINEHOUSE SMOKING CRACK VIDEO

We are hearing rumors that Rehab singer Amy Winehouse has checked into Rehab. While we are not sure, it would make sense after today's London Sun Newspaper video that shows Winehouse snorting something off a credit card. The Sun claims it was ecstasy and the video allegedly shows her smoking crack cocaine. A rep. for the singer told PEOPLE magazine "Amy is not in rehab, She was seeing a doctor who she regularly sees as part of her ongoing treatment. It was a regular appointment which she attends all the time. She has not checked in overnight."The rep, who would not comment on the nature of the treatment, did tell PEOPLE in December that Winehouse was "under supervision for both physical and all health issues."
