With the ultrasound circulating around the internet without her permission, Kailyn decided to confirm her pregnancy for herself in her confessional.

'I haven't really said anything publicly about it. I'm pregnant,' admitted the star, who gave birth to her second child with Lopez, son Creed, on July 30. 

'I have not talked to Chris, I don't talk to him. He has been in and out of jail. I think what has transpired over the last few months between Chris and I has just been so eye-opening.'

Kailyn tearfully explained that she decided to open up about her domestic issues with Chris because she knew 'people [would] have a ton of questions and [would wonder] how [she] could have gone back to someone like that.'

'I think there's a lot to be said that I haven't really talked about in a relationship where domestic violence is there and where it's just really toxic. I'm still trying to figure that stuff out,' Lowry alleged, as she wiped tears from her face. 

Kailyn insisted at the time of Tuesday night's episode that she 'had no intentions of including Chris in anything' going forward.

'As of right now, I have no intentions of including Chris in anything, and so going into this [pregnancy] knowing that he won't be there at all is really scary.'
