Online Jon Hamm is leaving the issues to Don Draper. The 44-year-old Mad Men star recently underwent treatment for alcoholism. TMZ reports that the Golden Globe winner and GQ ‘s April cover gent was treated for 30 days at the high-end Silver Hill Hospital in New Canaan, Connecticut. Hamm has been answering questions about the similarities and differences between himself and Draper—the booze-fueled, womanizing, riddled-with-demons ad man he plays on TV—for years now.
