'Teen Mom 2' Arrest: Jenelle Evans Assaults Nathan's Girlfriend! Water Poured On Her Head?

Who knew Teen Mom 2 star Jenelle Evans's trainwreck life could get any worse? Getting arrested twice this year wasn't enough for the MTV star. Just yesterday, she was taken behind bars for a third time after assaulting ex-fiancé Nathan Griffith's new girlfriend Jessica Henry. Will the drama ever end with Jenelle?

According to TMZ, the police were called after the mother of two violently flung a glass at Jessica's head!

"Nathan Griffith showed up at her South Carolina home to get his belongings. He brought along a new girlfriend, which didn't sit well with Jenelle," according to the gossip site. "We're told Jenelle came charging out of the house and threw a glass at the girl, striking her in the head."

The Ashley Reality Roundup has more information on the attack including what may have sent the reality star into a rage. While it is not confirmed yet, the site is reporting that Jessica may have pured water on Jenelle first which led to the glass throwing.

In talking to The Ashley, Jenelle's representative Johnny Donovan defended his client from what happened during the altercation.

"She's been really focused. She just got a new house in Wilmington, North Carolina," he said. "She's trying to move away from the drama, trying to move away from Nathan. She's been really focused and really positive, and then this happened today."

"I wasn't there," he went on. "But I'm sure they had an argument and when you provoke someone, they're not going to hold back and that's it."

Jenelle must have a great rep because he put the blame squarely on Nathan without mentioning any responsibility on behalf of his client.

"Nathan provoked her," he said. "That's what he does, he tries to make her look bad and he succeeded today. That's pretty much it."

Ironically, MTV aired a new episode of Teen Mom 2 Thursday night in which Nathan was arrested for his nasty blowup with Jenelle earlier this year.

 So "Teen Mom 2" star's fiancé was arrested yesterday...I took this pic while my daughter was out riding her bike. They're my neighbors but probably not for long. #teenmom2 #drama #staged
