Jenelle Evans' Mom Feuds With Her Boyfriend: 'Teen Mom 2' Trailer Shows Tense Interaction

Jenelle Evans' boyfriend still isn't getting along with her mom.

In the recently released trailer for the upcoming second half of Teen Mom 2 season five, Barbara Evans is seen threatening Jenelle's boyfriend and soon-to-be child's father, Nathan Griffith.

After Nathan is heard saying, "I'm f**king done," Barbara tells him, "You hurt my daughter I’ll be after you." In the June 19 report by Radar Online, it is also revealed that Nathan has to go to jail for 30 days because of his Sept. 2013 DUI charge.

Last season on Teen Mom 2, Barbara and Nathan had their differences and in one particular scene, Nathan was seen blaming Jenelle's issues with addiction on her mother's enabling. Things between them got ugly and screaming matches weren't out of the ordinary, but Nathan later apologized to Barbara for his out-of-line behavior. Unfortunately, the tension between them remains.

Also featured in the trailer are Leah Calvert's marriage troubles. During the first half of season five, fans saw as Leah and Jeremy bickered back and forth over Jeremy's work schedule, and while Leah claimed that things were better after filming wrapped, they are once again at odds in season 5B -- but this time it's over Jeremy's alleged control issues.

In a car scene involving Leah and Jeremy, Leah is seen in tears, shouting,  "You don't see the way you treat me. You f**king control my whole entire life."

Leah also claims to be drowning in medical bills for her daughter, Ali, who is suffering from muscluar dystrophy.

Teen Mom 2 season 5B premieres on MTV on July 16 at 10 p.m.
