When Briana DeJesus joined the Teen Mom 2 cast in 2017, she was not welcomed with open arms. In fact, she quickly became persona non grata at her first get-together with the cast – with one exception. Jenelle Evans, Briana said, “is the only one who was acting like her s–t ain’t stink. Plus she was the only one who wasn’t acting fake and choosing sides.” Leah Messer’s response was to “pay no attention to those who try to bring you down … they’re just envious of where you are and how well you’re doing.” As we’ll get to in a bit, relations haven’t exactly gotten more amicable in the months since.

Maci Bookout and Taylor McKinney’s relationship has produced three kids, and they seem very happily married … most of the time. Like, 85 percent of the time. Bookout alarmed fans with this confession earlier in the year that revealed some trouble in paradise: “Eighty-five percent of the time we’re good to go … Fifteen percent is hell. All of our stress and emotions, we take out on each other. When the cameras leave, we’ll drink and freak out. It’s always literally the smallest things. It’s such small stuff but it blows up. It’s not going to go away.” Yikes … but at least they are self-aware and working on things?

Things neared a boiling point between Amber Portwood and Matt Baier after he vowed that would never marry her … because she wouldn’t marry him on the spot in Las Vegas, obviously. “I will not marry her,” he said. “I will not marry her now, ever! I’m not gonna let her [brother] dictate my life. That f—king f—got. She wants to marry her brother. That’s who she wants to marry. F—k her. She just humiliated me on TV. I’m done!” Matt, who was livid at Amber’s reasoning for not eloping in Vegas – her brother Shawn not being present – went on to tell a producer, “I don’t care who you have to give oral pleasure to, keep the Amber and Matt wedding thing off [the air]. She just embarrassed me in front of 12 million people.” We’re pretty sure you did that to yourself, Matt …

Brooke Wehr was never a Teen Mom 2 cast member, but due to her mercurial relationship with Jeremy Calvert, her impact was felt just the same. Earlier this year, the couple’s engagement ended after Brooke accused Jeremy of cheating on her with multiple women, one being a Teen Mom 2 producer, another being her best friend, and a third possibly being his ex-wife Leah Messer. Oh yes. Brooke even shared a screen shot of a text message conversation between Jeremy and the best friend as proof, while Calvert responded in a drunken stupor that yes, maybe he did sleep with Brooke’s best friend, but … only because Wehr slept with some other guy first. Or, as he put it, Brooke was “f-cking his brains out, every day,” and he was single, so “my dick was happy to do whatever the f-ck it wanted to do, and it did.” Shocking that these two didn’t work out … but neither party was completely off base with their allegations. Just saying. Jeremy and Leah did hook up.

From the get-go, it’s been Jenelle Evans and husband David Eason against the world, but at times, they’ve been at each other’s throats as well. Arguments between the two were commonplace throughout recent seasons of Teen Mom 2, and one particularly heated argument resulted in them calling off their wedding … the night before the wedding. (They ultimately got married as planned.) Bad tempers are one thing, but the most troubling aspect is that David has been accused of mistreating/abusing Jenelle’s son Kaiser because he reminds him of Kaiser’s dad, Nathan Griffith. He also doesn’t get along with her mom, at all, further driving a wedge between the Evans women.

About as one-sided as a feud can get, but a feud just the same: Briana DeJesus got pregnant for the second time during a brief relationship with this guy, then promptly pulled the plug after discovering he was unfaithful. Luis’ public dressing down marked Briana’s return to the Teen Mom fold (she joined Teen Mom 2 for the first time this season following stints on Teen Mom 3 and 16 & Pregnant) and cemented her firebrand reputation. Probably the only positive thing, if you can call it that, is that she’s moved on to other feuds.
