VIDEO: Leah Messer Admits She Hooked Up With Jeremy Calvert in New 'Teen Mom 2' Episode

Teen Mom 2 star Leah Messer and her second ex-husband Jeremy Calvert are seemingly always on and off.

And as reported to OK! Magazine, the mom-of-three actually admitted to hooking up with Calvert again in a sneak peek of an upcoming Teen Mom 2 episode. In the clip, Messer is talking with her friend on FaceTime and mentions that Calvert showed up somewhere. Her friend asks if they hooked up, and she denies it. Her friend then asks if she is lying, and she admits she is, indeed, lying.

This isn’t the first time the former couple, who share six-year-old daughter Adalynn, have slid back into each other’s lives. They admitted during last year’s reunion episode that they hooked up on a trip to New York City, and that it wasn’t the first time.

Though the chemistry between them is undeniable, they are keeping a level head about their relationship. They're reportedly both on the same page about keeping it strictly physical so no one gets hurt. We will have to wait and see how well that works out for them.
