Although Natalie claimed she would not move to America to be with Mike, she did come to Sequim on 90 Day Fiancé season 8. This time, Natalie’s only goal was to get the engagement ring back and marry Mike. However, the cheating scandal resurfaced again midway through the season. While talking to a therapist named Rachel, Natalie shared that Mike was supposed to stay at his aunt and uncle's house during Sarah's final wedding preparations. However, on the morning of Sarah's wedding, she called him. She alleged that he answered her call “half-naked and stoned” from Sarah’s sofa. In the background, Sarah could be heard telling Mike, “I’m going to the show.”

Mike maintained that they were “close friends.” He and Sara used to “live together” and he had “watched her daughter grow up.” Sara wanted him to be her best man, so Mike had gone to her house to help. However, the groom ended up going out with his friends and staying at his own house. “Nothing has ever happened, never ever. Before, ever,” Mike maintained. Natalie seemed to believe him. Despite getting dumped before her own wedding ceremony, she married him in the 90 Day Fiancé finale. A loved-up wedding photo was taken.

However, Sarah shocked TLC viewers by appearing in the season 8 Tell-All part two. She was there to set the record straight. She said that jokester Mike and serious Natalie had cultural differences that made them incompatible. In terms of the wedding eve incident, Mike had flown in late on Thursday night. She had “multiple people” staying at her place for her Saturday wedding, and she stated that nothing happened with her and Mike. Sarah said that she and Mike have “never been romantic.”

 

Mike called Sarah his sister again. She revealed that her first introduction to Natalie after the event was not pleasant. When out to buy her wedding cake with Mike, he asked Sarah to speak to Natalie over FaceTime. She said Natalie asked her, “if all American women were wh*res,” or if it was just her. Natalie denied saying it multiple times but agreed that there was a screaming match.

Sarah wondered if Natalie’s insecurity was the result of her friend telling her that “women in America can’t have relationships with men unless they’re sleeping with them.” The showdown between 90 Day Fiancé star Natalie and Sarah ended on this bitter note. With Mike and Natalie returning to 90 Day Fiancé: Happily Ever After? season 6, there are bound to be more fireworks.
