"Teen Mom 2" 2015 is wrapping up its sixth season this Thursday night and the tension is at an all-time high between Kailyn Lowry and ex Jo Rivera when they once again meet to discuss their duties and responsibilities to their son, Isaac.

A sneak peek at the Season 6 finale episode of "Teen Mom 2" has been released via the reality series' official Facebook page, and from the looks of it the exes are once again engaging in a verbal exchange while discussing about their parenting over Isaac.

The teaser trailer begins with Kailyn and Isaac arriving at Jo's place. Kailyn does not waste time in questioning the kind of father Jo is showing to their five-year-old after he missed Isaac's graduation and other important events in the young one's life including the game that Rivera skipped.

Since Kailyn was very adamant in alluding that Jo is an absentee father, the later retorts with a tirade of questions rife with expletives.

"Whatever Kail. I'm not going to f--king argue with you about petty s--t. Like what do you want me to tell you?" Jo tells the mother of her son, as per InTouch Weekly. "Do you want me to hop back in my time machine and go back and change it? I can't so shut the f--k up and that's it."

At one point Kailyn asks her ex to shut up, but Jo insists that he is not shutting his mouth up. Kailyn then asks why he is cursing at her, and Jo drops the major bomb when he says, "Because you're an idiot."

Kailyn eventually points out in the "Teen Mom 2" sneak peek that when they sat down to talk about child support, Jo manipulated her into thinking that he couldn't afford it. The 23-year-old then straightforwardly says, "Don't ask me for a favor then...not to go to the court system and for you to pay me on top of what you owe."

Meanwhile, amid the tension over child support, Kailyn seems to be doing just fine. She recently let fans into her new home with Javi through her and her friend Sterling Black's lifestyle blog Live, Love, Linens, according to Wetpaint.

In her personal post, the "Teen Mom 2" star wrote: "A few months ago, my family and I bought a new home... a blank canvas for my interior design mind to run free!"
