Briana DeJesus and Kailyn Lowry reportedly went head-to-head during filming on the "Teen Mom 2" season eight reunion. Following rumors of a potential on-stage fight between the two reality stars, DeJesus is still upset at her co-star and recently continued their feud with a message to Lowry on her Twitter page.

"Mean what [you] say, say what you mean," DeJesus tweeted on May 21. "When [you're] ready to pop off, you don’t say anything..you just do it..

that’s #1 and #2 if I’m at arms reach, don’t walk around a 50 ft table. [You] cross it. Get it together! [Kailyn], [you] knew [you] weren’t gonna touch me."

Although Kailyn Lowry did not respond to her "Teen Mom 2" co-star directly, she did surface on Twitter just a few minutes after Briana DeJesus' tweet was shared.

In her post, Lowry wrote, to no one in particular, "Not a da** thing changed."

Did Briana DeJesus attack Kailyn Lowry at the 'Teen Mom 2' reunion?

While rumors swirled over the weekend which suggested that Lowry was attacked by DeJesus and her sister, Brittany DeJesus, Lowry has since confirmed that that was not the case. As she explained in a tweet, she wasn't beat up by anyone, nor did she get hit by anyone. That said, rumors continue to swirl in regard to what actually happened between the two women.

According to DeJesus' tweet, Lowry acted as if she wanted to physically fight her but when it came down to it, she didn't make a move. Instead, she allegedly talked crap [VIDEO] and refused to back it up.

Why don't Briana DeJesus and Kailyn Lowry get along?

Last fall, months after DeJesus joined the "Teen Mom 2" cast (after "Teen Mom 3" came to an end after just one season), she began dating Javi Marroquin, the former husband of Kailyn Lowry.

Right away, Lowry made it clear that she was not a fan of the coupling [VIDEO] and began feuding with DeJesus on Twitter and over text messages.

While DeJesus and Lowry have continued to feud with one another in the months since she began dating Marroquin, DeJesus' romance with Lowry's ex-husband ended several months ago, and, for the past few weeks, he has been involved in a committed romance with Lauren Comeau, who he first dated for a short time last summer.
