Can this chick get any more trashy?!!! We’ve seen her on MTV’s Teen Mom 2 fail at motherhood, assault her own mother, steal from her family, and NOW she’s beating a chick down that her boyfriend apparently hit on?!! Soooo crusty! Anyways, TMZ attained footage of the whole catfight…check it out after the jump…

(TMZ)–“Teen Mom 2” star Jenelle Evans ferociously ATTACKED another woman in North Carolina this week … while her scumbag friends cheered her on … and the brutal assault was all caught on tape.

19-year-old Jenelle is clearly the instigator — spewing all sorts of nasty insults at a woman named Britany … before the reality star suddenly socks the other woman in the face with a closed fist. The two women tussle to the ground … where Jenelle continues to pummel Britany … even AFTER it’s clear she can no longer defend herself.

Britany Truett tells us the gnarly fight was over a boy — aren’t they all? — who just happens to be Jenelle’s ex, Kieffer. She says Kieffer made a pass at her when the three of them were hanging out and Jenelle was not pleased.

Britany says she was shocked that Jenelle got so angry, since they have been friends for seven years and Brit has no interest in Kieffer.

Britany claims she has a bruise on her eye, scratches on her face and a bite mark on her breast. She says she’s spoken to Jenelle since the fight went down, but only through Facebook … in messages she described as Jenelle “smack talking.”

Britany tells TMZ she has no plans on pressing charges and just wants the whole thing “to go away.”
