'Things Escalated!' Briana DeJesus SLAMS Kailyn Lowry Over Violent Fight

Briana DeJesus is explaining her side of the violent Teen Mom 2 brawl against Kailyn Lowry.

In a sneak peek clip for the reunion special, Briana sat down with Dr. Drew to discuss the fight that went down when they attempted to film the Unseen Moments. "It just escalated. Things escalated. I said s**t that I probably shouldn't have said," Briana admitted.

Dr. Drew wanted to understand the feud more and asked, "Like what? Did you cross some boundaries, some line?" Briana explained, "No she crossed mad boundaries with me! That's my whole point."
