These pix are a little concerning.

We caught Jon Hamm at a bar in LA last night, and it looked like he was indulging in a beer. While that would normally be no big deal, it's a bit of problem considering he has reportedly been sober since going to rehab for alcohol addiction in 2015. We guess it could have been non-alcoholic beer, or a super frothy Martenelli's cider, though!

The Mad Men star sounded like he had kicked his battle with the bottle after getting treatment.

"It has all these connotations, but it’s just an extended period of talking about yourself. People go for all sorts of reasons, not all of which are chemically related. But there’s something to be said for pulling yourself out of the grind for a period of time and concentrating on recalibrating the system. And it works. It’s great," he told The Journal shortly after completing a program.

This might not be his first slip-up, though! Page Six spotted him drinking wine with rumored new lady love Dakota Johnson at the Viceroy Central Park hotel in NYC in early October.

Brad Pitt should reach out to him and give him some pointers!
