Jenelle Evans throws a bit of a fit during the Teen Mom 2 season six reunion.

Is 'Teen Mom 2' Star Jenelle Evans' Ex-Fiance Planning To File For Custody Of Kaiser?

As she and her mother, Barbara Evans, discuss custody issues with Nathan Griffith and Dr. Drew Pinsky, who hosted the reunion special, Evans storms off set after her mother accuses her of waiting six years to regain custody of her son, Jace.

"Six years later? Oh really, mom?" Evans fires back. "Look at you. You work at Walmart deli and I'm going to be a medical assistant saving people's lives while you serve f**king food. F**k that. I'm done with this s**t, dude."

Is Jenelle Evans Using David Eason To Make Her Ex-Fiance Nathan Griffith Jealous?

"God, always being put down, whether it's my mom or Nathan, one of the two," Evans continues as she walks off set.

Then, when producers attempt to calm her down, Evans says, "How can I chill when she's talking about how she deserves my son? F**k her, dude. She doesn't deserve anyone. She doesn't deserve anyone's love, no one's affection, no one's care. When I was pregnant she called me a wh**e!"

Although Evans and Griffith were together at the time the reunion special was filmed in July, they split weeks later, and have both since moved on, Evans with David Eason, and Griffith with Jessica Henry.
