Party Animal! Leah Messer Caught Getting Boozy Post Rehab!

Leah Messer just left rehab and she's already been spotted out partying with friends!

The Teen Mom 2 star smiled in photos with her friends, who were drinking at a bar and even taking shots.

In May 2015, Leah checked into rehab to deal with stress and depression, but both her ex-husbands claimed it was because of an addiction problem to prescription pills.

Leah is a mom to three daughters and faces criticism for her parenting often on social media.
