VIDEO Leah Messer and Corey Simms spar over Miranda, infidelity in Teen Mom 2 Reunion preview

After a season of Teen Mom 2 that saw tensions steadily rising between Leah Messer and Corey Simms, it’s no surprise they both had a bit of steam to let off at the Teen Mom 2 Reunion… But, dang, it sure got intense! In a new preview clip, the former spouses sparred over Miranda Simms, Leah’s parenting and rumors of infidelity. That was until Leah abruptly ended the conversation with her safe word, “Monkey.”

To start things off, Leah said she and Corey got along great until Miranda came into the picture. Corey said that was because his new wife gave him “the backbone to stand up to your bulls**t.”

“Miranda gave you a backbone?” Leah questioned. “You want to get started on Miranda?”

After Dr. Drew said he wasn’t sure that line of questioning was “fair,” Corey said Leah has issues with Miranda because she’s “jealous” of their “normal, functioning life.”

Leah strongly disagreed, saying, “Never in my life would I be jealous of Miranda.” Then she really pulled out the big guns by asking Corey, “Where were you at during the first couple months of marriage?”

But Corey wasn’t backing down and instead told Leah, “Let’s go there. I’m not scared of you anymore… If I did the s**t that she does, I wouldn’t see my kids.” Even though Dr. Drew asked Corey to elaborate, Leah interjected with “monkey,” which they explained is the safe word she wanted to use when conversations steered into dangerous territory. Dr. Drew said, “There is stuff she doesn’t want to go into.”

See how it plays out in next Wednesday’s Teen Mom 2 Finale Special, which airs on MTV at 9/8c.
