Mad Men’s Jon Hamm has undergone treatment for alcohol addiction, the Associated Press reports. The Emmy-nominated actor did so with the support of his longtime partner, actress Jennifer Westfeldt, and they asked for “for privacy and sensitivity going forward,” in a statement from Hamm’s publicist. TMZ adds that the rehab stint took place at Silver Hill Hospital in New Canaan, Connecticut. Hamm reportedly checked himself in last month for a 30-day program. The news comes ahead of Mad Men’s final season, which begins April 5 on AMC.
