The Ashley‘s sources are saying this is the craziest Reunion filming in Teen Mom history and, after what went down during the Teen Mom 2 Reunion taping today, The Ashley agrees!

Just one day after Jenelle Evans‘ husband, David Eason, whipped out a pocket knife while filming a ‘Teen Mom’ party segment, he was allegedly involved in a major altercation (along with Jenelle and her ex, Nathan Griffith and a few others) that shut down production and upset some of the cast and crew!

The Ashley’s source tells her that the Reunion filming was underway on Saturday when the fight broke out.

“Most of the cast was in various green rooms backstage and the kids were all running around playing together,” The Ashley’s on-set source tells her. “The fight started when Nathan’s girlfriend [Ashley Lanhardt] was walking past the room Barbara [Evans] was in. Barbara hugged Ashley goodbye and Jenelle saw it and came bursting out of the room.

“She yelled at Barbara that it was wrong for her own mother to hug Nathan’s girlfriend,” the source added.

From there, madness reportedly broke out.

“Nathan jumped in and was defending Ashley, and that’s when Jenelle called David in,” the source said. “She yelled that Nathan was being out of control. That’s when one of the female producers stepped in between Jenelle and Ashley.

“The kids were all running around during this huge fight, and someone in the cast grabbed Kaiser and took him away from the scene,” the source said. “Because the fight was in the hallway, some of the other cast members were basically trapped inside the rooms they were in. Some of the other parents were really concerned and barged out of the green rooms to find their kids and bring them somewhere safe.”

Another person that was nearby tells The Ashley that, at one point during the argument, Nathan reportedly accused Jenelle of being high. Jenelle also reportedly accused Nathan’s mom, Doris, of being high. (She was present during the fight but The Ashley doesn’t know how she was involved.)

Multiple sources have confirmed to The Ashley that the fight shut down production temporarily because producers and the security team were trying to break things up.

“No one actually threw a punch, luckily,” the source added.

The Ashley hears that the entire fight was filmed, so we will almost certainly get to see it all go down on a future episode!

While ‘Teen Mom 2’ Reunions have always had hi-jinks, this time the producers (and some of the other cast members) were very upset about what went down, particularly because most of the kids saw the fight.

“Several cast members–even some of the dads– made the statement that this was not a safe place for kids to be, with stuff like this happening,” the source said.

UPDATE: Both Jenelle and Nathan have addressed the fight on their social media accounts. Jenelle confirmed that the fight did happen, but stated that Nathan’s girlfriend started it. Nathan and his girlfriend denied this and posted a video explaining their version of what happened.
