Mad Men star Jon Hamm has completed a stint in rehab for alcohol abuse.

The actor was treated for 30 days in the Silver Hill Hospital in New Canaan, Connecticut, TMZ reports, after he checked himself into the facility at the end of February.

A representative for Hamm told the publication: "With the support of his longtime partner Jennifer Westfeldt, Jon Hamm recently completed treatment for his struggle with alcohol addiction. They have asked for privacy and sensitivity going forward."

The final season of the AMC drama Mad Men, in which Hamm plays the lead role Don Draper, will air next month.
