According to People, Winehouse's father, Mitch Winehouse, urged his daughter, who has done numerous stints in rehab, to seek treatment. "Her dad sat her down and said, 'I think you're drinking too much again,'" a source told the magazine. "So she agreed to do an assessment to stop it becoming a bigger problem."The singer checked in to the Priory Wednesday — but not before downing a miniature bottle of Smirnoff vodka en route to the clinic "in typical Amy style," the source said.Winehouse's summer gigs kick off June 18.
