Teen Mom stars Kailyn Lowry, and Briana DeJesus are going at each other once again. The two reality stars have never been the best of pals, but on Sunday, the two began going at each other once again in a very vicious nature on social media.

According to InTouch, Kailyn Lowry hoped on her Instagram page on Sunday, sharing a pretty bizarre maternity photo of herself posing completely nude with a horse. Needless to say, many of Kail's social media followers were pretty stunned and very confused as to why Kail chose that particular shot to share. Lowry had since deleted the photo, but not before Briana DeJesus had a chance to throw some serious smack talk towards Kail.

This instantly reignited the Teen Mom's former feud, and things have gotten seriously nasty really fast. Reality fans are well aware that Kail and Briana share an ugly past when it comes to feuds. In 2015 the two moms got into some ugly arguments over Javi Marroquin (Kail's ex and Bri's affair.)

Things remained so bad between Lowry and DeJesus that during the 2018 "Teen Mom 2" reunion filming, the two women became physical with each other causing a huge ruckus on the set and amongst the other Teen moms. No one actually threw a punch, but, according to Lowry, she really wanted to smack DeJesus around.

Kailyn Lowry not taking Briana's insults lightly

The reason the two mom's got so out of control, according to Kailyn was that Briana had accused Kail's ex and baby daddy Chris Lopez of physically abusing Kail in front o her kids. Lopez responded to the accusations on social media, denying all claims that he had raised his hands towards Kail.

Things quieted down for a while, but on Sunday, Briana DeJesus brought up the painful subject once again. The two women continued their back and forth clams against each other, bringing up every painful detail they could in order to hurt the other.

Even Kail's friend Bone Estrada got in on the action telling Briana that the "only one getting their a$$ beat was her" and posted "See you at the next reunion." DeJesus did not seem too concerned about Bone's worded threats and snapped back, stating that they would never cross paths after what happened before adding they would not even be in the same building on the same day.

'Teen Mom 2' drama kicks up once again

Later that evening, Bri sent out another tweet claiming that she did not mean to spark up a fight with Kail. Adding, she thought her photo was cute, adding the final dig, "I thought the horse made the picture."

Kailyn Lowry recently revealed she was pregnant with her fourth child. Lowry also claims she has been receiving a whole lot of new hate over the pregnancy from some of the Teen Mom followers. Lowry claims she does not understand why some people are so full of hate.

Despite all the word bashing via social media between Kailyn Lowry and Briana DeJesus, a couple of things look to be certain, these two are never going to ever get along, and the next season of "Teen Mom 2" should be quite an interesting venture for all involved.
