Another day, another depressing news item about Teen Mom.

In an Us Weekly sneak peek of the upcoming episode, Leah Messer, the 23-year-old mother of three, reveals while in rehab that she's finalized her divorce from her second husband, Jeremy Calvert.

"Our divorce is final," she tells her mother on the phone. "With Jeremy and I, just like, something just didn't feel right. And I stayed because I didn't want the embarrassment of another divorce. But you know what, I'm letting it go."

Television audiences first met Messer on 16 & Pregnant, when she conceived twin girls just a few months after starting to date boyfriend Corey Simms. She and Simms got married in 2010 and divorced in 2011. By Christmas that year, she was engaged to Jeremy Calvert, and they welcomed their first child in 2013. Messer checked into a rehabilitation program for stress and depression in June of this year.
