The sneak peek shows the 24-year-old fuming after picking up her 21-month-old son from Nathan's house — and realizes that her ex-fiance's new lady love has trimmed her son's blond locks!
After Jenelle was fuming about the haircut in the car, her friend Tori Rhyne asked how the reality star was so sure it was Jessica who took scissors to her child's head — to which she responded:
"She's a f*cking hairstylist, Tori…I am so heated right now."
C'mon, Tori, keep up!
The momma was so heated about missing out on her son's first haircut, she ended up calling Nathan to lay down the law — and said that if he wanted to see his son in the future, "you can take me to court for visitation."
Yikes! Someone's a bit snippy…
