'Teen Mom 2' Leah Messer Accused by Corey Simms of Endangering Daughters! [WATCH]

Teen Mom 2 star Leah Messer's ongoing custody battle with ex-husband Corey Simms seems to be getting worse. In a preview clip for this week's episode, the MTV stars sit down together to hash out a plan to split time with their twin girls Ali and Aleeah.

In a sneak peek of episode four, Corey is shown being worried about his ex's parenting skills when he doesn't have his daughters.

"If I have them for that extra little bit, that's an extra little bit that I don't have to worry about it. I don't want you to take this the wrong way, but that's time that I don't have to worry: 'Are they tardy?' or 'Are they late?' Or 'Are they there, or are they not?'" the reality dad said, via The Inquisitr.

The conversation gets even worse when Corey shocks fans by retelling a story where one of the twins had to make breakfast for herself while Leah was sleeping. The upsetting part was the 5 year-old was using a very hot toaster by herself!

"I was a sick a couple weekends ago and eating toast, and Aleeah's like, 'Oh I know how to make a toast.' I'm like, 'How the hell do you know how to make a toast? How do you even know how to use a toaster?' This is what she said. She said, 'Cause my mommy's a sleepy head, and I have to make myself breakfast,'" the West Virginia dad retold. "Whenever your child says that, and she can show you how to make toast in a toaster to back up what she said, that's hard!"

As MStars News reported, Leah recently threw some Twitter shade at her babies' daddy when she complemented her second ex-husband's parenting skills and not Corey's.

"@calvert505 is hands down one of the best dads that I know. Couldn't imagine coparenting with anyone else. Addie ALWAYS comes FIRST!" the reality star wrote.

Do you think Corey should get more custody days of his twin daughters?
