The 90 Day Fiance Instagram account 187Anonymousgossip re-posted the video of Juliana's response to the question on Wednesday.
"Ugh, guys, I wasn't married to him! We just lived together," Juliana explained of Kayque. "And Luigi was 45, and he was just my boyfriend."
Juliana, a 23-year-old from Goiania, Brazil, therefore insisted neither of her two men ever were her husband.
Juliana is currently starring on Season 7 of 90 Day Fiance on TLC with Michael, a 41-year-old independent and self-employed wine entrepreneur from Greenwich, CT.
The couple met a few years ago at a dinner party on a yacht in Croatia, and 90 Day Fiance's currently-airing season will document Juliana coming to the United States on a K-1 visa with the intention of marrying Michael and staying permanently in America.
After meeting in Croatia, Michael and Juliana experienced two difficult years of dating, during which they had both been denied tourist visas.
When Juliana finally had her interview in Rio de Janeiro to obtain her K-1 visa, she told 90 Day Fiance cameras, "They just asked stupid questions. They asked me if I had been working as a prostitute the last 10 years."
Michael was upset Juliana had been insulted, and he confirmed, "No, she's not a prostitute!"
Michael added that it's normal for young models to travel the world and party with wealthy people. He worried at the time Juliana's visa would be denied and they'd have to continue making a long-distance relationship work.
However, both individuals held out hope they'd be able to live together one day.
But Michael acknowledged their romance would continue to be an uphill battle even if Juliana was afforded the opportunity to come to the United States.
Michael and Juliana's time together had been fun and exciting, and she had only seen pieces of Michael's life -- not the full scope of his responsibilities, including being a father to two children, Max and Cece.
Michael and Juliana hadn't discussed how things were going to be or what was going to happen once she arrived in America, so Michael anticipated daily life might be a struggle and potentially a huge reality check for Juliana.
Michael also wanted Juliana to learn the value of a dollar and appreciate how hard he worked to support them both.
