As you may have heard, there was a little incident that took place in the Teen Mom universe this weekend.

A pretty huge incident, actually.

We're talking, of course, about how Kailyn Lowry and Briana DeJesus decided to pull a Farrah Abraham and Amber Portwood at the taping of the Teen Mom 2 reunion on Saturday.

And by "pulling a Farrah Abraham and Amber Portwood," we mean their feud got physical.

So far, we've heard reports from sources about what went down, and Kailyn's offered a few words of explanation.

But now Briana is telling us exclusively the full, detailed story about what happened.

And it is INTENSE.
