Teen Mom Stars and Their Kids

"You're not gonna talk to me like that," Chelsea tells her ex's mother.

Chelsea Houska ended her ninth season of "Teen Mom 2" with a bang on Tuesday night, as she got into it with her ex's parents over visitation.

Currently, Houska and husband Cole DeBoer have custody of Aubree, who she shares with Adam Lind. He's only allowed to see her at school events or for supervised visitation, while his parents are given one visit a month, at which Adam can't be present.

On the season finale, however, Lind's mother Donna called Chelsea to feel her out about changing the agreement. She hoped Houska would allow Adam to be present when Aubree goes to their home and apparently became confrontational when Chelsea wouldn't budge.

Since Adam's mother did not agree to be on camera, viewers didn't hear her side of the conversation with Chelsea -- but Houska's responses and conversation with her husband after did a pretty good job filling in the blanks.

"I truly don't feel like enough steps, I haven't seen any steps on his end to be okay with that quite yet," said Houska, after Adam failed to show up for scheduled time with Aubree at a visitation center last season. "He could go to the visitation center again and set up visits again."

"Are you wanting him to have time with her or is he wanting to have time?" she then asked, with Donna presumably saying it's something she wanted. "It would have been different to hear he wants to see her, from him."

After another unknown comment, Chelsea told Donna, "You're not gonna talk to me like that. The final word of it is I'm not comfortable. I'm not comfortable with it, I guess."

Following the phone call, both Chelsea and Cole were fuming. "I can't believe what I just heard," DeBoer told his wife, "I'm shaking because I'm f--king so mad."

He also filled in a few blanks by claiming, "She flat out just said on the phone that he didn't ask for more time with her." Chelsea, meanwhile, said she was offended Donna was trying to "make me feel like I'm making the wrong decision."

Speaking with Chelsea's father later, the two claimed Lind's mother said "it's time Chelsea stops punishing" Adam for his failures in the past. Donna also apparently said the current arrangement was "inconvenient for her."

With Aubree recently celebrating her 10th birthday, her dad cracked, "You only have 8 more years of this!"
