Things are getting snippy on Teen Mom 2!

In a preview for the Monday, March 28, episode of the MTV docuseries, Jenelle Evans freaks out when ex Nathan Griffith’s girlfriend, Jessica Henry, gives the former couple’s son, Kaiser, 21 months, a haircut.

In the clip, Evans, 24, goes to pick up Kaiser from Griffith’s mom’s house where she realizes her former fiancé's new squeeze has taken scissors to her little guy’s curly blond locks.

“I’m so mad. Jessica cut his f--king hair,” the reality star fumes to her friend Tori Rhyne in the above clip. “Look at his bangs!”

“Cut my f--cking child’s hair? Really?!” she continues, before Rhyne chimes in, “How do you know she did it?”

“She’s a f--king hairstylist, Tori,” the young mom fires back. “I am so heated right now.”

Without hesitation, the Wilmington, North Carolina, resident calls Griffith, 27, to give him a piece of her mind.

“So you wanna take it upon yourself to have Jessica cut Kaiser’s hair?” she yells over the phone. While the retired Marine denies his lady love is responsible for Kaiser’s new 'do, Evans isn’t buying it.

“Who cut his hair?” she questions. “Like, this is insane. And you know what? I’m changing my number right now, and if you want to see Kaiser, you can take me to court for visitation. Goodbye.”

Unable to hold back her emotions, Evans turns to her gal pal to lament. “That’s his first haircut and I wanna be there for that,” she says. “And I wanna take pictures and everything.”

Since splitting from Griffith in 2015 after a brief engagement, the TV personality has struck up a new relationship with David Eason, who will appear on season 7 of Teen Mom 2.

As previously reported, Evans is simultaneously fighting two custody battles: one with Griffith over Kaiser, and another with her mother, Barbara, who currently serves as the legal custodian for the TV personality’s 6-year-old son, Jace.

Watch the sneak peek in the video above. Teen Mom 2 airs on MTV Mondays at 10 p.m. ET.
