AceShowbiz - Celebrities will take the great length to do anything for publicity, including faking romantic relationships. There has been a lot of celebrity couples that people doubt to be real and the recent example is YouTube stars Jake Paul and Tana Mongeau, whose whirlwind romance surprises everyone.

Tana, who previously was in a polymary relationship with Bella Thorne and Mod Sun, revealed she was engaged to the social media influencer after the latter popped the question on her 21st birthday in June. The bride-to-be took to her Instagram account and revealed her new fiance had proposed with a cake that had "Will you marry me, Tana?" written on it.

Unsurprisingly, people thought they were not serious but Tana was quick to clarify the rumors. It seemed like fans were not the only ones who were not exactly convinced by their relationship as Jake's brother Logan Paul appeared to shade the now-married couple during his radio performance.

When stopping by Barstool Sports podcast on KFC Radio, the YouTuber explained how a fake relationship works before advising Tana to go away from Jake should their engagement be really fake. "There's no exchange [of money], but you can make money together. Like, say you make merch together, you probably split like 50/50 split, I hope so," he said. "Like what if my brother's like doing 80/20 with Tana? Oh Tana no, Tana don't do it. He been doing 80/20."

Despite the rumors, Jake and Tana proceeded with their Las Vegas nuptials and allegedly let the camera roll for a reality TV show. But the wedding didn't put a stop on the fake relationship speculations. Logan once again hinted that all this was done for publicity after sounding skeptical about Jake's romance. When asked if his brother's marriage would last, Logan said, "No," adding he gives it a "month, month and a half." Furthermore, Tana said that the wedding wasn't legally binding on paper.

In other cases, people suspected that one relationship was fake because the couple worked on a collaboration together. For this reason or another, here are other celebrity couples whose relationships are deemed fake by most people.
