Amy Winehouse In Rehab?

Less than 24 hours after a British tabloid posted home movies showing her smoking crack and rambling incoherently, Amy Winehouse went to a London rehab facility -- but there's some debate about whether or not she's checked in for the long haul. London's Sun tabloid reports that the singer is, in fact, staying at the private London clinic, but People magazine quotes Winehouse's publicist as saying "no, no, no." The flack tells People, "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."
