Leah Messer will talk to ex Corey Simms— but NOT his wife Miranda Patterson!
In a preview clip for the upcoming season finale of Teen Mom 2, the troubled mother of three, 23, drives to meet up with her former husband and baby daddy for the first time since her release from rehab.
"I'm just so nervous. I hope I'm ready for this conversation, because I don't feel like I am," Messer tells her cousin Chastity and friend Brianna, who have joined the ride for moral support.
As they pull up to the meeting spot, the girls spot Patterson in the restaurant window.
"This is f***ed up!" Messer says. "I'm not doing the conversation if Miranda is here!"
The conversation presumably concerned the former couple's 5-year-old twins, Ali and Aleeah Grace, who were under Simms' care while Messer received treatment out of state for her anxiety and depression, but what RadarOnline.com has confirmed is a prescription painkiller problem.
Messer and Patterson have been at odds all season, with Simms' pregnant wife even doubting that rehab could work for the MTV starlet.
Now, a shocking rumor has brought a new understanding to the women's bitter feud.
According to In Touch, Messer and Simms secretly had sex in his truck during a meeting to discuss custody issues.
"He's admitted the affair to Miranda," an insider revealed to the magazine. "It's a huge mess and all their friends know about it."
The Ashley's Reality Roundup confirmed the report, adding that the naughty tryst occurred late last year, while Messer was still married to ex-husband #2 Jeremy Calvert. (The parents of 2-year-old Adalynn divorced in June.)
