Leah Messer Posts 'Teen Mom 2' Reunion Announcement On Facebook

On Teen Mom 2 season six, Messer is seen dealing with accusations of drug use and cheating as her divorce from Jeremy Calvert rages on. While Messer and Calvert don't actually split until the end of filming, fans are getting to see the beginning of the end play out on the show.

On tonight's new episode, Messer will be seen undergoing a drug test for her custody battle with Corey Simms to prove she isn't taking any drugs, other than the medication prescribed to her for headaches.

After receiving news of having passed the test, Messer told her lawyer, "I told [Corey] from the beginning, I mean, I knew it would come back negative. I guess I was aggravated that they pushed so hard. I just think they are trying to dig and dig to find something wrong, but they're not going to find anything. I'm going to be honest."

Teen Mom 2 airs Thursdays at 10 p.m. on MTV. For a sneak peek at tonight's new episode, check out the video below.
