Rumours are rife that "Teen Mom 2" star Leah Messer's ex Corey Simms is all set to exit the show as he doesn't want to deal with any more drama on television. Messer's second, Jeremy Calvert, is expected to follow suit.

"Corey is done with the show," a source told Life & Style, reported OK!Magazine. "He told MTV he will not return for another season."

Simms is reportedly ashamed of his ex's behaviour and he "doesn't think the money is worth the aggravation anymore."

"Jeremy also wants out of Teen Mom," the source added. "But he hasn't made any formal moves yet."

One of the recent episodes of "Teen Mom 2" saw Simms accusing Messer of being a bad mom as their daughters are always late to school. He has also been arguing about splitting the custody of twin daughters Ali and Aleeah.

"If I have them for that extra little bit, that's an extra little bit I don't have to worry about," Simms told 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."

He went on to add that he wasn't fine with Messer allowing the children to cook for themselves while she slept in.

"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?'" Simms recalled. "She said, 'Because my mommy's a sleepyhead and I have to make myself breakfast.'"

A recent episode of the show saw Messer spanking one of her kids for acting out and not listening to her.

"You're not gonna act like this in front of people. Do you understand? I've had enough," Messer says before taking Aleeah into a private room and spanking her. She later admitted to feeling bad for spanking her daughter. "I had to spank her. I feel bad because I spanked her."
