The 90 Day Fiancé franchise stars are followed around in their natural environment, and some of their gross habits have disturbed a few viewers. After being on air for eight years and over 16 spin-offs, viewers are familiar with a wide range of characters from the franchise. Some stars like 90 Day Fiancé's Michael Ilesanmi and Syngin Colchester were more laid back. Then there were stars like Jasmine Pineda or “Baby Girl” Lisa Hamme, who had a difficult time controlling their jealous tendencies.

On the other hand, some stars lived more lavish lifestyles, like Stephanie Matto. Meanwhile, others lived with their parents as they saved money for their own homes, like Brandon Gibbs and Julia Trubkina. Viewers have seen these 90 Day Fiancé stars from Russia, Nigeria, Dominican Republic, and more, all from the comfort of their homes. However, one thing most of them have in common is their habits.

Some reality stars, such as 90 Day Fiancé's Bilal Hazziez are a little more high-strung in the cleaning department. Others, like Ella Johnson, lived on a farm where dirt and grime were inevitable. Nonetheless, most stars had average habits. However, there were a few whose habit's were so gross that viewers had to do a double-take at what these 90 Day Fiancé stars were doing.

Mike Berk

Mike Berk and Ximena Morales on 90 Day Fiance: Before the 90 Days

When Mike Berk first appeared on 90 Day Fiancé: Before the 90 Days, he seemed to be a sweet, wholesome man who would do anything for his then love interest, Ximena Morales. Little did Ximena or viewers know the turmoil that would ensue. A couple of weeks into their time together, Ximena realized many gross habits Mike exhibited. From farting and burping on top of her to leaving his dirty clothes around like a child, 90 Day Fiancé's Mike clearly lacked manners. Some viewers became uncomfortable after he tried to tuck his snotty tissue into the taxi seat.

Big Ed Brown

Big Ed: 90 Day Fiance

Much like Mike, Big Ed Brown was single for most of his life and the “why” became more apparent after appearing on three seasons of the 90 Day Fiancé franchise. Big Ed is renowned for his cringeworthy moments, like when he gifted Rosemarie Vega, who was 23-years-old at the time, with lingerie and a toothbrush, or when he blurred the lines of decency by inviting Kaory to his room after a shooting in Mexico. However, he really disgusted viewers with his “Ed and Shoulders” creation. Since Before the 90 Days' Big Ed began dying his hair, which made his scalp dry. As a remedy, he showed how he roughly applies globs of mayonnaise with a spatula onto his hair and lets it soak.

Paul & Karine Staehle

This riotous couple hasn’t been on the show within the last few years, but they’ve maintained their stance in the headlines. Paul and Karine Staehle first appeared on 90 Day Fiancé: The Other Way. Aggression, accusations, and annoyance fueled their relationship. During one of their infamous videos, fans saw a glimpse into their home and were not impressed. As Paul had Karine smell some fishy crab meat, viewers saw their house closely resemble those from the famous reality show Hoarders. Fans quickly became revolted as they noticed the stained couch and cluttered space the couple shared with their two sons.

In Paul from Before The 90 Days and his wife Karine’s case, the situation is a little more understandable. With two toddlers, it’s not always easy to keep the house sparkling at all times. Additionally, Big Ed only wanted to keep his hair healthy, but there are better ways to do that. Mike, on the other hand, is a little more questionable, as he clearly lacks some basic etiquette Regardless, the habits add to the unique dynamic of the 90 Day Fiancé franchise that viewers have grown to enjoy.
