Pedro Jimeno

90 Day Fiance Pedro and chantel

Pedro Jimeno was subjected to one of the most notorious mothers-in-law in the franchise when he married Atlanta beauty Chantel Everett. Chantel’s parents ruthlessly and excessively hounded Pedro and accused him of using Chantel to "harvest the American dollar." The wild accusation led to seasons of bad blood that extended into The Family Chantel. Though Pedro eventually befriended Chantel’s family, he first had to deal with serious questioning and interrogations that were led by Chantel’s dramatic and erratic mother Karen. Meanwhile, Chantel clashed with Pedro’s mother Linda and sister Nicole. Chantel’s verbal brawl with Nicole resulted in Chantel calling her sister-in-law a “bitch-a**, slut-a** wh*re,” which has become one of the most memorable lines in the entire franchise.

Larissa Lima

Larissa Dos Santos Lima from 90 Day Fiancé

Larissa Lima’s Brazilian bombshell personality clashed wildly with the ultimate smother-mother, Debbie Johnson. The mother of Larissa’s ex-husband Colt notoriously disliked sharing her home with the Brazilian woman when she joined Colt in the United States. Debbie was fiercely protective and possessive of her son in an oddly close dynamic that has been mocked by viewers. Meanwhile, Larissa also clashed with Colt’s relatives who questioned her intentions with the mama’s boy. During one argument, Larissa infamously yelled “who is against the queen will die.” Debbie went on to also clash with Colt’s following partner, Jess Caroline. Debbie is considered by many viewers to be a nightmare mother-in-law who is jealous of her son’s romances.

Elicia inappropriately inserted herself into affairs between Deavan and Jihoon. A particularly memorable explosion occurred when Deavan accused Jihoon of failing to watch her daughter properly, which resulted in the young girl running off. Elicia and Deavan then verbally attacked Jihoon in a tense explosion. Elicia was accused of berating Jihoon, ordering him around and meddling in his marriage with Deavan.

The issues between Andrei and Libby’s siblings have turned the family against each other as Libby always sides with her husband at the expense of her siblings. Libby and Becky even threw fists during a family yacht outing because Becky was insulting Andrei.

Kalani Faagata from 90 Day Fiancé

Though Kalani’s close-knit family has caused issues in the couple’s marriage, the problems pale in comparison to what issues Asuelu’s money-hungry mother posed. Lesina and Asuelu's sister Tammy demanded the couple pay them $1,000 during a family visit in Washington. Asuelu and Kalani were struggling financially and unable to meet the full demands of his family. This led to Lesina and Tammy arguing with Kalani and accusing her of turning Asuelu against them.

She continued to make Natalie’s life difficult last thanksgiving by bringing the vegetarian to a butcher and allegedly calling her a hooker.

Trish majorly crossed a boundary in the opinion of many viewers by telling Mike, “Give her $5,000 and send her back to the Ukraine.”
