In a sneak peek of Teen Mom 2, Jenelle Evans freaks out over the fact that her ex-fiance Nathan Griffith’s new girlfriend gave their son Kaiser his first haircut.

Upon picking up Kaiser with her friend Tori, Evans realizes Kaiser’s hair has been cut. When Tori asks how Evans knows Jessica did it, she told her she’s a “f—king hairstylist.”

Evans was emotional when she said she wanted to be there for her son’s first haircut; document it and take photos of the occasion. So she called Griffith and told him she was keeping Kaiser and changing her number and if he wants to see his son he can take her to court.

Teen Mom 2 airs Mondays on MTV.
