Mad Men and Bridesmaids actor Jon Hamm has reportedly completed a 30-day stint in rehab for alcohol addiction.

The star checked himself into the Silver Hill treatment centre in Connecticut last month, and has recently returned home after completing the four week programme.

A spokesperson for Jon confirmed the news to gossip site TMZ, saying the actor would like the issue to be treated with sensitivity by the media,

"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," said the rep.

Since leaving rehab Jon has made a number of promotional appearances for Mad Men, including an event earlier this week to unveil a Don Draper tribute bench in New York. 

The actor has previously spoken about the dark time he went through following his father's death when Jon was just 20. "I struggled with chronic depression. I was in bad shape," he revealed in an interview in 2010. "But I was very fortunate to have really good friends in my life whose parents sort of rallied."

The final series of Mad Men begins next month. Jon also currently appears on the Netflix series Unbreakable Kimmy Schmidt.

We wish him all the best with his recovery.
