While the baby daddy’s name has yet to be revealed, Kail put Javi on full blast during the live Teen Mom 2 after show by calling him out for breaking into her basement.

“It was uncomfortable and unexpected,” she said. “I don’t want to go through it again. It was crazy. I hope we both move on.

“I feel bad he hasn’t moved on as quickly as I did,” Kail went on. “Javi believes every single rumor. How many times can I say sorry about what I’ve done? I can’t apologize for something I didn’t do. He can’t believe everything he hears.”

Following Kail’s slam fest, Javi went on a Twitter rant about her comments: “It’s not possible,” he tweeted. “I don’t need your ‘friendship’ don’t play mother Teresa now,” adding, “Friendship and co-parenting are two different things.”

As Star reported, Kail was granted a protection from abuse order following the break-in. The two share 3-year-old son Lincoln.
