First, Leah Calvert said she wasn't coming back to Teen Mom 2, now reports are saying that she is. Then, the original Teen Mom cast had their own major shakeup when it was reported that Farrah Abraham wouldn't be returning for the show's reboot in 2015. A few months later, it was rumored that she WOULD be coming back if the show got picked up for another season.
While Leah hasn't confirmed her on-again status, Farrah did respond to all of the speculation regarding her casting status.
In response to a report that said Farrah had been calling producers non-stop promising them that she'd change and begging them to take her back, Farrah tells RumorFix, "Not true and that is a lie, I have no need to change [and no need] to call people."
So, it sounds like Farrah's time on Teen Mom is officially over.
As for Leah? We'll keep you posted.
