Winehouse "has embarked on a treatment program at the Priory Clinic. She wants to be ready for performances in Europe this summer and decided to seek an assessment. She will remain at the Priory on doctors' advice," the rep said in a statement.
A source close to the singer told the magazine that it was her father Mitch Winehouse who coerced her to go to rehab. "Her dad sat her down and said 'I think you're drinking too much again.' So she agreed to do an assessment to stop it from becoming a bigger problem."
That didn't keep Winehouse from one last hurrah: she reportedly downed a miniature bottle of Smirnoff vodka on her way to the clinic, "in typical Amy style," said the source.
