Leah Messer seems to think that her ex-husband, Jeremy Calvert, is hoping to rekindle their romance. In a sneak peek at the upcoming second half of the eighth season of "Teen Mom 2," Messer is seen chatting with her younger sister, Victoria, about Calvert's behavior, claiming he keeps posting messages on her social media photos and acting "super weird."

"Jeremy texted me and said he wants to talk to me," Messer tells her sister in the clip shared by Pop Culture. Although Messer says that Calvert may want to talk to her about their daughter Adalynn Faith's upcoming birthday party, her sister says that Calvert would like to go to dinner and possibly try and work his way back into her life.

"He asked me to do [Adalynn]'s birthday party together," Messer explained. "Maybe that's what it's about." Then, when Victoria brought up the idea of Jeremy Calvert attempting to get back together with Leah Messer, Messer said that she "sure as hell" hopes not.

Leah Messer was hooking up with Jeremy just months ago

During a February interview on her "Teen Mom 2" co-star Kailyn Lowry's podcast series, "Coffee Convos," Messer admitted that her physical relationship with Calvert hadn't come to an end when she and Calvert divorced. She then said that while she and Calvert were still hooking up, she didn't have any plans to rekindle their romance. After all, they were married once and they weren't happy together.

According to Leah Messer, she and Jeremy Calvert make great friends and simply aren't the best when they are in a committed relationship with one another.

They are also great co-parents to their four-year-old daughter.

Jeremy Calvert has a new girlfriend

Since then, Kibler has made headlines for getting two DUIs in one night and for being accused of drug possession during the arrest [VIDEO]. On Twitter, Kibler has mentioned her arrest, claiming she made a mistake and continuously gushing over her love for Calvert. She even sparked rumors of an engagement with a ring emoji.
