Jon Hamm went under the radar and completed a 30-day stint in rehab for alcohol abuse last month, and on Wednesday evening we saw the Mad Men star out and about for the first time since he checked out of Silver Hill Hospital in New Canaan, Connecticut.

Hamm kept his head down, and though he tried to cover up his face with the brim of his baseball hay, we couldn't help but notice how gaunt and exhausted he looked. Hopefully he's going to rest up and relax over the next week -- after all, the final season of his hit AMC show premieres on April 6, so he will undoubtedly be attending a number of events to promote it.

Last week Jon's rep confirmed that the actor had checked in (and out) of rehab and said in a statement, "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."

There have been a handful of blind items about the star, and in 2011 The Enquirer ran a story detailing his hard partying ways. "On the set, Jon’s always as sober as a preacher. But when he’s not working, he likes to cut loose with a drink or two… or more! By the end of night, he often seems blotto. His nickname is 'Hammered,'" a source told the tabloid.

We're glad he sought help!
