'Teen Mom 2' Jenelle Evans Cheating Accusation Led To Bloody Fight With Nathan Griffith! MTV Cameras Were There, Did They Capture The Breakup Blowup?

Teen Mom 2 star Jenelle Evans has been through hell the past few weeks after getting arrested for driving without a license and then getting into a bloody fight with fiancé Nathan Griffith. Now, it seems the altercation between the MTV stars happened because Nathan was cheating behind Jenelle's back!

"He's been talking to another girl for two weeks," a source told E! News. "[Nathan] felt like he cheated on someone and then admitted he's been seeing someone else for two weeks."

This led to the MTV mom staying at a nearby hotel to get away from her dishonest partner. When Jenelle came home, according to E!, Nathan tried to get his engagement ring back from her by pinning her "up on the toilet seat" and "wrestle" her for it. According to the police report, little Kaiser's father took the ring off of Jenelle's finger, which made her bleed.

Even though the MTV camera crew was at the home filming, they told police they didn't see anything because they were outside. The police report went on to say "MTV security came into the residence due to [Jenelle's] screaming during the altercation."

The mother-of-two isn't "sticking up for him" because they're "completely over," the E! source said. "It's over and she is looking for an apartment for her and the baby [Kaiser] today."

"It was a big deal but wasn't a big deal," the source continued. "He didn't intend to hurt [Jenelle] on purpose, but he shouldn't have wrestled her or touched her, period."

Nathan was arrested on charges of domestic violence, but he denied ever touching the reality star.

As MStars News reported, trouble between the recently engaged pair had been brewing for quite a while. We even predicted the MTV couple was on their way to a train-wreck breakup in our Feb. 28 report.

"Nathan has her so controlled, it's sickening," a source told Radar Online. "He's a control freak. It's crazy. He controls her life."

"He won't even let some of her relatives see the new baby as much they want," the source went on. "They're constantly fighting."

Cheating has always been the number one issue brought up when they are fighting in their hostile relationship.

"He loses his mind over every little thing that Jenelle does," according to Radar. "He's jealous, but HE's the one talking to other girls and then he gets mad when Jenelle calls him out."

Who do you think is telling the truth in regards to the fight: Jenelle or Nathan?
