On the last episode of Teen Mom 2, a disheveled Leah Messer finally fed her children dinner at midnight and ignored her screaming toddler as objects fell on her head.
Now, in a new MTV preview clip, the 23-year-old mother of three's first ex-husband, Corey Simms, expresses his concerns about her parenting over pizza.
While advocating for more custody time of their 5-year-old twins Ali and Aleeah, Simms, 25, argues that the girls are in safer hands with him.
"If I have them for that extra little bit, that's an extra little bit I don't have to worry about," he tells his former wife. "I don't want you to take that the wrong way, but that's time I don't have to worry, are they tardy, are they late, are they there, are they not."
When the two-time divorcee claims she can't parent effectively if her ex watches her too closely, Simms goes on the offensive.
"I was sick a couple weekends ago, and I was eating toast, and Aleeah says, 'Oh, I know how to make that.' I said, 'How the hell do you know how to make toast? How do you know how to use a toaster?'" he recalls. "She said, 'Because my mommy's a sleepyhead and I have to make myself breakfast.'"
"Whenever your child says that and she can show you how to make toast with a toaster to back up what she said, that's hard!"
"It's not really that big of a deal," Messer responds.
He then adds that in order to gain his trust back, the girls have to stop showing up late to school 10 times a month.
A paranoid Messer then accuses Simms of planning to take the girls away from her.
"It feels like someone has a plot against me or something like that," she says. "At the end of the day, it's my kids, my life. I have to do what I have to do."
As RadarOnline.com readers know, just three months after filming in March, Messer headed to rehab for what sources say was prescription painkiller abuse. (MTV reps claim she underwent treatment for depression and anxiety.)
Now, she currently shares custody of Ali and Aleeah with Simms, and also coparents 2-year-old daughter Adalynn with second ex-husband Jeremy Calvert, 27.
As Radar reported, both exes are not expected to make a legal move unless she messes up motherhood once again.
