Jon Hamm has completed treatment for alcohol addiction, his publicist has confirmed.

The Mad Men star, who plays hard-drinking advertising executive Don Draper in the hit TV show, asked for “privacy and sensitivity” following the revelation.

It is unclear when Jon Hamm sought treatment, but he did so with the support of his long-time partner, actress and film-maker Jennifer Westfeldt.

Jon Hamm has recently been seen promoting the final season of AMC’s Mad Men.

According to TMZ, which first reported the story, Jon Hamm was treated for 30 days at the Silver Hill Hospital in New Canaan, Connecticut.

Jon Hamm, 44, has been asked to compare himself to his Mad Men character several times over the series’ eight-year run.

“I don’t drink as much as Don Draper,” he told the Daily Mail in 2012.

“I would be unconscious if I did.”

However, Jon Hamm also admitted he turned to alcohol after his father died from complications of diabetes in 1991.

Jon Hamm – who was 20 at the time – was left without parents, having lost his mother 10 years earlier.

“It just changed everything,” the actor told GQ in 2014.

“It was just a profound sense of being alone. And that lasted a while.

“I was in college, and I had to start over again. I started drinking; it was a rough time.

“I was at a crossroads. It really could have gone the wrong way.”

Jon Hamm has roles in two high-profile Netflix series: Playing doomsday preacher Reverend Richard Wayne Gary Wayne in Tina Fey’s critically-acclaimed comedy Unbreakable Kimmy Schmidt; and starring in the upcoming Wet Hot American Summer, a prequel to the 2001 cult indie comedy about a rowdy summer camp.
