Teen Mom 2 star Leah Messer dropped a bombshell while filming for an upcoming episode of Coffee Convos podcast with Lindsie Chrisley and Kailyn Lowry — she is definitely hooking up with ex-husband Jeremy Calvert again!

"She revealed she and Jeremy have been hooking up, and that it is not going to stop anytime soon,” a production insider revealed to Breaking Celebrity News exclusively.

But unfortunately for fans who were rooting for the former couple, a separate source told Breaking Celebrity News the reconnection isn't serious.

"She says that they are just having fun and she’s got it all under control," the source insisted.

The two weren't trying to hide their rekindled romance on Instagram live this week. During their session, the exes were very flirty.

Messer, 25, and Calvert, 29, divorced in 2015 amid the MTV star's rehab stint and battle with depression and anxiety. The single dad infamously accused his wife of cheating with her ex on Twitter the year prior, and Breaking Celebrity News exclusively reported his affair with tattoo model Melissa Marie.

The exes co-parent daughter Addie, 5. (Messer also has 8-year-old twins Ali and Aleeah Grace with first ex-husband Corey Simms.)

To hear all the juicy details about the hookup, tune into next week’s episode of Coffee Convos with Lindsie Chrisley & Kailyn Lowry, available on iTunes.
