90 Day Fiance is a show about people finding each other across continents and oceans, giving up everything for love.
Naturally, it is filled with some of the most toxic couples and the most vitriolic feuds that you can imagine.
Not all of that bile plays out on camera, either.
Behind the scenes and on social media, 90 Day Fiance stars will wage verbal wars on each other.
Sometimes, it's a rival from their season or a person who was almost family.
Other times, it's people who have only met once or twice, but experience loathing at first sight.
Take a look below and see the most intense feuds that have ever played out among the stars.
90 Day Fiance has a wealth of feuds
Fans may start watching for the controversial couples and the cute couples, but the feuds will keep you hooked for years -- because that's how long they can last.
First, let's address something obvious
A lot of these feuds involve Larissa Lima. Though she only entered the scene in Season 6, her relationship was the most talked about since Danielle and Mohamed. Her situation has changed, but for a long time, she was feuding with anyone who looked at her crossways.
First of all ...
We're not going to count every pair of exes on this list. Sometimes, they parted on good terms. Other times, they loathe each other but it's not quite feuding. But Colt resolved to try to get Larissa deported to Brazil, and Debbie is badmouthing her left and right. So we'd say that Larissa is feuding with them both, even though she is trying to move on.
Fernanda vs Larissa
Viewers who didn't keep up with the stars on social media at all were introduced to this feud at the Tell All special. Larissa saw Fernanda as her rival for the title of best-looking 90 Day Fiance star. It was so bad that Larissa and Colt were late getting on set.
Jonathan Rivera got involved
Though he and Fernanda would split several weeks after the Tell All was filmed, he had his wife's back and feuded with both Larissa and Colt. On the tell all, this culminated in the hilarious moment when Larissa yelled "shut upee!" It broke the tension -- a little.
That didn't last
When Jonathan and Fernanda's marriage fizzled out in December, they didn't really share joint custody of their feuds, either.
But now, that has changed
In March, when 90 Day Fiance blogger David Yates jokingly suggested a celebrity boxing match between Colt and Jonathan (not to be mean, but these are not men with equal degrees of athleticism, and that's all that I'm going to say about that), Jonathan replied -- perhaps in jest -- that he's down for it if Colt is.
Colt has yet to respond
There is an extremely real chance that he didn't see the post. Maybe he's too busy flirting with women on Instagram. There's a real chance that he was nursing a killer hangover during the days on which that conversation took place.
Moving on: Ashley Martson
Ashley got a lot of flack from a lot of her castmates and other 90 Day stars after it was discovered that Jay, with her knowledge, had been running an account that was "leaking" their personal photos. In other words, it looked like a ploy for sympathy. No one wants to be made to feel like a fool. But Ashley had one feud in particular ...
Ashley Martson vs Larissa Lima
Larissa claimed that Ashley was speaking poorly of every woman on the show to her. Whether this was true or simply something that Larissa said to stir the pot is anyone's guess.
Kalani Faagata vs Colt Johnson
In late 2018, Colt was asked if he had quit his job, and he replied that he had not -- that he was not Kalani. (Kalini, who clearly comes from a wealthy family, did quit her job ... but she has a baby, another baby on the way, and Asuelu is still getting adjusted to life in the US) Her response to Colt's shade was ... profoundly harsh.
Kalani hit back:
"Oh, Colt, sending “dick” pics and videos to women who aren’t your wife isn’t an occupation, silly," she wrote, just days after his cheating scandal and the leaking of an alleged, unimpressive photo. "Maybe you’re just perturbed my clitoris is bigger than your “dick”? I guess we’re even, though, ’cause you got me beat in the t-ts department." Colt started that fight, but Kalani finished it. He blocked her after that.
David Toborowky vs Debbie
In late February, David -- who is active and generally well-received in the 90 Day Fiance fandom even though we're well past his season -- and Colt Johnson's mom, Debbie, began feuding online.
Debbie called David a "piece of s--t"
However, David wrote that he didn't believe that she wrote it. He speculates that Colt used her account to write it so that he wouldn't have to personally face the blowback as he had in past feuds, such as his attempt to "roast" Kalani.
Jay Smith vs Larissa Lima
The fallout from Larissa and Colt's scary, violent breakup won Larissa a lot of sympathy, especially as fans continue to learn more about Colt. But Jay doesn't feel that way. Despite having once been rumored to be facing deportation himself, Jay shared on Instagram that he hopes that Larissa does end up getting sent back to Brazil. Rude! Clearly, he remembers her behavior from the Tell All.
As for Paola Mayfield ...
She's well-liked by fans (except for the people who shame her for having a human body or for working as a model), but she also took some shots at Ashley Martson after Ashley's fraud scandal blew up. But her most heated contention was with someone who's been in the franchise a lot longer. ...
Paola Mayfield vs. Anfisa Nava
These women were co-stars on 90 Day Fiance: Happily Ever After? Paola and Russ welcomed their first child while Anfisa's husband, Jorge, was in prison, so their lives went in different directions. Nonetheless, Anfisa quit the franchise and called out Paola and Russ for being "TLC's little b--ches." Pao and Russ replied that Anfisa was asking for unreasonable, Kardashian-level sums of cash.
Leida Margaretha vs Tasha Rosenbrook
Leida swept into Tasha's life, emotionally blackmailed Eric Rosenbrook into forcing his teenage daughter to move out of her own apartment (Leida threatened to leave him if he didn't, and she did this on speakerphone in front of Tasha). 90 Day Fiance viewers and stars alike were absolutely appalled.
That feud hasn't gone away
Tasha no longer has a relationship with her dad. Viewers heard her voice break on 90 Day Fiance when she realized that she'd lost that part of her family. Tasha found a new place to live, but she can't just go out and find a new dad.
Also, the feud got worse
Leida was granted a restraining order against Tasha -- which goes on Tasha's record and could hurt her chances on her next rental application or job application. Now, Tasha has to waste her limited resources fighting that in court. Just one more thing that Leida has taken from her.
Fernanda Flores vs ... JAX TAYLOR?
There's plenty of crossover in the world of reality television, but this was such a weird one. For some reason, Jax Taylor decided to hurl insults at Fernanda and Jonathan back when they were married. Jax said that Fernanda was a "fool" and said that Jonathan "looks poor." Jonathan may not have the wealth of Lisa Vanderpump, but he is a successful realtor and was making bank long before he went on reality TV. There's no love lost between those exes and Jax.
Jesse Meester vs Jon Walters
Owing to the fact that being hot is not a substitute for being a good person, Jesse is one of the most disliked dudes in the 90 Day Fiance fandom. Jon poked fun at Jesse's "tiny" package online, and Jesse called him out, accusing him of name-dropping Jesse as a ploy to build up clout. Very mature, guys.
Jon Walters vs Jay Smith and Ashley Martson
Like we said, he seems to have a bit of a temper when it comes to social media -- in real life, however, he seems to be a super decent guy. But when Jay and Ashley's fraud scandal was uncovered, he was one of those who felt duped and betrayed. And he used the C-word to refer to them both. To be honest, coming from a british dude, that's not a big deal. They use that word like punctuation.
Mohamed Jbali vs Danielle Mullins
Mohamed and Danielle are the toxic couple who are credited with putting 90 Day Fiance on the map. Their feud included accusations of cheating, accusations of stealing, and one party trying to get the other deported -- and they were doing this years before Larissa and Coltee. They've moved on -- and no, Danielle did not succeed. Mohamed is living and working in Texas.
Mohamed Jbali vs Ricky Reyes
Mohamed helped a friend of his with their music video. Innocuous, right? Ricky Reyes, who broke a woman's heart on international television as a ploy to promote his own production company, lashed out online.
Ricky called Mohamed a "little punk"
We haven't seen evidence that Mohamed had promised to do anything with Ricky. Also, Mohamed is trying to steer clear of "fame" these days. If you look at his social media, he's mostly just going to work and getting paid and living his life. Ricky has different goals, but ... they don't need to feud over it. No matter how much it amuses Danielle.
