MTV 'Teen Mom' Star Caught Brutally Beating Woman in Front-Yard Brawl

Jenelle Evans, the star of the MTV reality series "Teen Mom 2," is under investigation in North Carolina after video surfaced today showing her brutally beating another girl in an all-out, outdoor brawl.

In the video, Evans can be seen confronting the girl -- who apparently goes by "Britany" -- and launching into a verbal assault. Eventually, after some of Evans's alleged friends encourage a physical confrontation, Evans punches the girl in the face. From their it's chaos, as TMZ reports:

The two women tussle to the ground ... where Jenelle continues to pummel Britany ... even AFTER it's clear she can no longer defend herself.

With Britany bleeding from her face, one of Jenelle's scumbag friends pulls the reality star off the other woman ... while Janelle continues to drop verbal insults.

It's unclear why Jenelle wanted to fight Britany ... but sources connected to the incident claim it had something to do with Jenelle's boyfriend.

"This matter is under investigation and we are working closely with the Brunswick County Sheriff's Department," Brunswick County District Attorney John David told E! News. He also said that reports that the victim won't press charges will not affect the investigation.

According to E! this isn't the first time Evans has been in trouble: "She is due in court for a hearing on April 14 to face drug charges and a count of breaking and entering. On April 29, she'll be back on additional counts of breaking and entering, injury to real property, trespassing and making harassing phone calls."

She's been filmed in a physical altercation before. During the airing of "Teem Mom 2," she was seen shoving her mother, Barbara, during an argument:

She eventually gave Barbara custody of her 2-year-old son, Jace.
