Teen Mom 2’s Leah Messer has had a rough year, but it will reportedly end on a high note after getting back together with her ex-husband, Jeremy Calvert.

The couple, who share 2-year-old daughter Adalynn, finalized their divorce in September while the mother of three was in rehab. She then lost custody of her twins with Ali and Aleeah, 5, to ex-husband Corey Simms.

“They really missed each other,” a source told InTouch. “They recently started hanging out again an awful lot, and they ended up getting really close.”

Messer recently split from her boyfriend Theodore “T.R.” Dues, so friends are urging her to take it slow this time around with Calvert.

“Leah is known to make impulsive decisions,” the source said. “But everyone is crossing their fingers that they can make it work this time.”

Earlier this month, they were both seen at Messer’s daughter Ali’s choir concert, where onlookers said “they were acting like a happy family.”
