Jenelle Evans' relationship with her mother Barbara has always been a volatile one - and things haven't changed. In a sneak peek for tonight's Season 7 premiere of MTV's hit reality series "Teen Mom 2," Barbara attempts to make conversation with her daughter while she's waiting to pick up her grandson Jace, but Jenelle blows up and makes her mom cry.

In the clip, Jenelle sits outside of her home with her friend Tori as her mom pulls up in the driveway. Barbara attempts to catch up with Jenelle and asks her about her current problems, which include her fussy infant Kaiser (whom she shares with ex-fiancé Nathan Griffith), her custody battle with both Barbara and Griffith and her charges stemming from a physical altercation with Griffith's new girlfriend.

"So, how's Kaiser?" Barbara asks about her grandson.

"He is sick," Jenelle says, sounding annoyed. "He does not feel good. He won't eat, he won't take his bottle, he won't drink juice. He's been awake since 6 a.m." Barbara suggests that Kaiser might be in pain.

"No. He's fighting his sleep," Jenelle says curtly in front of Tori. "Stop telling me how to parent."

Sensing her daughter's anger, Barbara tries to change the subject and asks about how things are going with Jenelle's assault charges for the incident with Griffith's girlfriend.

"I don't know, I don't have any idea," Jenelle says, cutting her mother off. "I have no idea about anything. I don't know about your court date..."

Barbara interrupts, reminding Jenelle that they don't have a court date set for the custody hearing even though she had a lawyer write up an agreement almost two months ago.

"Three things that I don't want to talk about," Jenelle says and counts off on her fingers. "Nathan and custody, you and custody and then my pending charge. And you're coming here talking about this now."

"Nathan and custody?" Barbara asks, sounding confused.

"Can you just shut up and let me complete a sentence before you speak your mind?" Jenelle retorts.

"Why are you so rude to me?" Barbara asks and starts to cry. "I come all the way up here and you do nothing but be rude."

"And there you go, crying again as usual," Jenelle says coldly.

"Because you always hurt my feelings - I come up here and all you do is be mean to me," Barbara wails.

Barbara tells her daughter to go get Jace from inside so she can leave, and Jenelle and her friend Tori go inside, leaving Barbara alone outside.

"God dude, another argument," Jenelle says, then hugs and kisses Jace goodbye, sending him off without saying goodbye to her mother.
