The feud between Kailyn Lowry and Briana DeJesus shows no sign of letting up. If anything, it may be worsening by the day.
In fact, last night's Teen Mom 2 reunion show gave us a clear indication of just how intensely these two dislike each other.
It all started with rumors that Briana is dating Javi Marroquin.
But now it appears the co-stars have numerous reasons to distrust one another, and the mutual ill will goes even deeper than fans thought.
Check out our full rundown of the MTV co-stars' rapidly escalating feud, including last night's developments, in the gallery below:
Kailyn Lowry: Suspicious From the Start?
When it was first announced that Briana would be joining the cast of Teen Mom 2, her co-stars were reportedly less than pleased. Briana believes the reason for their reluctance was that Kailyn had sown the seeds of mistrust.
Briana and Kailyn: Best Frenemies?
At one point, it was rumored that Kailyn and Briana were close friends. Fans even alleged that they coordinated their plastic surgery procedures.
Now We Know Better
It now appears that while they knew one another and followed each other on social media, Kail and Briana were never actually close. The same can't be said of Briana and Javi Marroquin...
We don't know exactly when Javi and Briana hit it off, but they quickly became more than friends.
The Rumor Stage
At first, the co-stars would do club appearances and post on one another's social media pages, but would deny that they were romantically involved.
These days, we know that Javi and Briana are dating (or at least hooking up). And it seems the relationship has really complicated Briana's relationship with her co-stars...
On the DL?
On last night's reunion show, Kailyn initially played it coy when discussing her relationship with Javi. Of course, the special was filmed last month, so it's possible the two of them weren't dating yet.
“Javi and I and my family have a closer connection than Kail and I,” DeJesus said when asked about her relationship with Javi and her feud with Kailyn.
Briana proceeded to throw some shade at Kailyn, saying, “I feel like I’m the new girl so I got that high school vibe. Certain people are salty about certain things.”
It's All Kail's Fault (According to Bri)
Briana claims it's Kailyn's fault that the other moms on the cast don't like her.
"Some Type of Way"
“Kail is feeling some type of way about it,” she said. “Because Kail is feeling some type of way the other girls don’t want to be my friend.”
Will They Ever Make Amends?
Asked by host Dr. Drew Pinksy if she could envision a future in which she and Kailyn are friendly with one another, Bri replied bluntly: “It’s not going to happen. We tried today and it’s not working out.”
Kail & Javi: What's Up With That?
So why is it that Kailyn has such an issue with Javi and Briana? Could it be that she still has feelings for her ex-husband?
Javi: Still Hung Up On Kail?
Whatever the case, it seems Javi still has some very strong feelings about Kailyn.
Things Have to Change
“There’s a lot of things that have to change,” Javi said last night when asked about his relationship with Kailyn. “I will never be able to move on in a different relationship if that line is never crossed,”
He's Not Alone
It certainly sounds as though Javi isn't quite ready to move on from his relationship with Kailyn. And he's not alone on that score...
Say It Ain't So, Jo
Lowry's first baby daddy, Jo Rivera, is currently dating Vee Torres, but it seems he's still caught up in his feelings for Kailyn, as well.
“I don’t like seeing her with other men,” Jo admitted on last night's reunion. And he was referring to one man in particular, of course...
Chris Lopez: Still Causing Trouble
For someone who wants nothing to do with Teen Mom 2, Kailyn's most recent ex, Chris Lopez, is sure making a stir. It seems both Jo and Javi got upset when they learned Kail was involved with Lopez.
So is Kail's apparent magnetism at the heart of her feud with Briana? Is DeJesus angry that Javi is still so fixated on his ex-wife?
Kailyn Wants None Of It
Whatever the case, it seems Kailyn is done with drama for the remainder of 2017. Prior to last night's show, she tweeted, "Goodnight Twitter," seemingly to indicate that she would not be watching. Boss move.
