Kailyn Lowry vs. Briana DeJesus Fight Details: What REALLY Happened at the Teen Mom 2 Reunion?

At this point, you're probably aware that Kailyn Lowry and Briana DeJesus "fought" at the taping of this year's Teen Mom 2 reunion show.

Now, as another season comes to an end and another reunion show approaches, new details are emerging about exactly what went down between the longtime rivals.

Did Kailyn and Briana really come to blows?

Was one of their castmates so disgusted by the escalating violence that she threatened to quit the show?

Is Bri's sister really the ultimate attack dog?

Join as we answer these questions and more in our breakdown of this long-awaited title fight.

1. Kail on the Side

Sources say Kail had resolved to distance herself from the drama at the taping that took place back in May. Obviously, that was an unattainable goal.

2. Spilling the Tea

Kail opened up about the events of the reunion on a recent episode of her Coffee Convos podcast, and as you may have guessed, things got seriously ugly.

3. The Showdown

According to both reports from both women, Briana and Kailyn nearly came to blows on two separate occasions.

4. Backing Down

The first such occasion saw Kailyn approach Bri and threaten her. But when the time came to "throw hands," as Bri puts it, Kailyn simply wasn't up to the task of socking one of her co-stars in the face ... or so DeJesus says.

5. Growing Up?

That's a good thing, obviously, as violence that's not in self-defense is generally something only crazy people resort to. Which is why producers keep Jenelle Evans around.

6. Round 2

The Second time they came face-to-face, Briana reportedly attacked Kailyn. And this time, there was no backing down ...

7. Call Security!

However, there were guards in place to ensure that this reunion special didn't deteriorate into a UFC fight.

8. Briana Drama

Clearly, Ms. DeJesus preferred to let her fists do the talking. Unfortunately for fight fans, the beef was quickly squashed by security.

9. In Front of Everybody

According to witnesses Briana went after Kail on stage during what was supposed to be a segment in which all of the moms briefly discuss their feelings toward one another.

10. On the Attack

"Briana was the last girl called to the stage, and she came out and went right at Kail," one witness tells The Ashley's Reality Roundup.

11. It's Brittany, Bish

That's when Briana's sister, Brittany DeJesus, jumped into the melee. Unlike Bri, it seems she was actually able to lay hands on Kail.

12. Brittany vs. Kail

"She jumped in and got in Kail's face. They started swinging at each other and Kail was motioning to Bri to 'Bring it on!'" says the onlooker.

13. Kail Confirms

"Brittany ran up behind me and pulled my hair. That was it," Kailyn said while offering her version of events on her podcast.

14. The Bri Defense

Amazingly, Kail actually defended Briana, informing listeners that her longtime rival "didn't do anything." Of course, she also took the opportunity to throw some shade ...

15. The Almost-Throwdown

Addressing the topic of her earlier confrontation with Briana, Kailyn claimed that she challenged her rival to a fight, but Bri backed down.

16. Kail's Version

Lowry says she "confronted [Briana] alone and she would not get up. I just wanted to hash it out. But she did not want to. We went into a private room without cameras and I told her to get up."

17. Bri Backs Down?

"She wouldn’t get up and that was that," Kailyn added. Needless to say, Bri doesn't come off looking terribly tough in that version of events.

18. Chelsea Lately

Chelsea Houska, who is currently pregnant with her second child, was reportedly so disgusted by the events of the reunion that she refused to return for a second day of filming and threatened to quit the show completely.
