Watch the Crazy Fight at Jake Paul and Tana Mongeau's Wedding in Las Vegas

It wouldn't be Jake Paul and Tana Mongeau's wedding if there wasn't at least some sort of drama.

On Sunday, an apparent fight broke out during the YouTube stars' controversial ceremony, which took place at the Graffiti Mansion in Las Vegas, a little over a month after the couple announced their engagement.

After Paul 22, and Mongeau, 21, exchanged their vows, which was live-streamed for thousands of fans online, the couple leaned in for their first kiss as husband and wife when a guest supposedly threw champagne at her Glaudi by Johana Hernandez dress. This didn't go over well with Paul and officiant Arman Izadi. "What the f--k, bro?" Paul was heard yelling in the vid, before he jumped in.

The two men appeared to fight the champagne-thrower. A scuffle soon ensued as more people got involved. See the wild video for yourself, above.

"A dude came up and threw champagne on Tana and Jake and Jake pushed him and our priest Armani, I don't know how else to say this, he beat the shit out of him," Paul's brother Logan said of the brawl, according to People. He also added that he didn't know who the champagne-thrower was. "He was smiling all menacingly."

After security broke up the fight, which only lasted a few minutes, Paul and Mongeau were able to share their first kiss as a "married" couple.

Following the incident, however, fans began questioning whether the entire fight was a set up as many people, even Logan, have questioned the legitimacy of Paul and Mongeau's relationship from the beginning.

"I give it a month," Logan told reporters outside the reception, per People. "It seems a bit hasty, in my opinion. It seems a bit preemptive, as one might say."

However, Mongeau has expressed the marriage and relationship is nothing but authentic.

"Jake and I finally sat Logan down and really had a talk with him about how real everything is and he started to cry," she told E! News last week. "And I never thought I'd be in a position where I was making Logan Paul cry, so to know that he finally believes it and is emotional about it makes me so happy, so I'm so excited to see him at the wedding. He's actually going to be Jake's best man and we're super pumped about it."

"I don't really care about anyone's opinions at this point," she added. "I think that no matter what you do on the Internet, there's always going to be people who are going to scrutinize it, don't believe or ask you a thousand questions about it. And if you live your entire life in this position, trying to prove what's real and what's fake, you'll absolutely never be happy."

"For me, I love Jake and I'm very excited to do this and we're both having a lot of fun," she concluded. "I'm happy and that's all that really matters to me."

She then addressed the scrutiny (again) on Twitter just days before the wedding.

"i'm feeling feisty," she wrote. "i don't care if u think my wedding's real. i don't care if u think my marriage is real. i don't care if u think Jake and I don't love each other. i don't care if u think getting married fast is a bad idea. i don't care if you think it's gonna last. OOPS!"
