'F**k Me Up To My Face!' Briana's Sister Drags Kailyn By Her Hair During Epic Fight

The biggest fight in Teen Mom 2 reunion show history has finally aired! On this week's special Teen Mom 2: Behind The Screams, Kailyn Lowry versed Briana DeJesus and her sister Brittany on the reunion stage!

Before the taping, Lowry welcomed co-star Chelsea Houska on her podcast Coffee Convos. The two discussed the upcoming reunion during the get-together.

"Briana's mouth is reckless," Lowry said. "She commented on Instagram that my son's father beats my a** in front of my children. You're making false allegations directed at people you don't know, talking about my children."

Lowry explained how she wants to "hit her," but "doesn't feel like having a mug shot and charges." She then said, "At this point I don't think I would be able to control myself."

DeJesus also vented about Lowry before the reunion.

"I don't care for her," she said. "I get it, I messed around with your ex-husband. But you guys got a divorce. That relationship is over. I see you maybe twice a year."

For the Unseen Moments special, Lowry texted DeJesus to see if she would want to talk in a "safe" place.

Lowry could be heard saying to DeJesus, "Why don't you tell me why you felt so comfortable commenting what you commented on Instagram. This isn't about Javi anymore, this isn't about the show. I want to know why you felt you were comfortable enough to say some s**t about my kids and about Chris."

DeJesus yelled back, "Relax! I'm going to do what I want to do. I'm going to say what I want to say. If you don't f**king like it then that's it. What the f**k is your problem? You're not going to do s**t! B***h, stay the f**k away!"

DeJesus then tried to break through security to fight Lowry, but was held back.

While filming the Unseen Moment special, DeJesus stormed on stage and screamed, "Now you're not going to do it in front of the cameras? Now you don't want to do nothing!"

"I'll fight you," Lowry said as she stood up. "I'm trying to get to you."

When Lowry went around the couch to go passed security, DeJesus' sister Brittany then went behind Lowry and pulled her to the ground by her hair.

"Let me go!" DeJesus screamed to security.

"She wouldn't do s**t in the room when it was just me and her," Lowry said. "Now everyone's here and you wanna act all tough. Brittany's got to come up behind me to get me. Your sister has to fight your battles b***h."

"Stupid b***h," she said. "Basic b***h! Stupid b***h!"

Lowry screamed to the cameras, "You want to come f**k me up? F**k me up to my face."

DeJesus' feud with Lowry began when she started dating her ex-husband Javi Marroquin. The two dated from October 2017 before officially ending it in January 2017. Lowry was married to Marroquin for nearly four years.

As for Jenelle Evans, she skipped the reunion because her husband David Eason wasn't allowed on set. Eason was fired from the series for making homophobic comments.

"David can't go and I don't want to be around the drama," she told her friend. "No one gets along anymore and it's a bunch of cat fighting. We have gotten along at one point. I don't know where things went wrong."
