Woman exposes groom-to-be as a cheater in viral TikTok after spotting him on his bachelor party in Las Vegas - but leaves the internet divided by outing him

A TikTok influencer was enveloped in a firestorm of controversy after reporting that a man had cheated on his bride-to-be during his Vegas bachelor party.

Tiana Wiltshire, a personal trainer and nutrition coach, uploaded a TikTok video Sunday to share her findings. The clip quickly went viral, and as of Thursday night, had garnered nearly 24 million views.

In the clip, Wiltshire claimed a man cheated on his fiancée at the MGM Grand casino in Las Vegas on March 9, though she left out any salacious details.

'If your fiancé just went on his bachelor trip to Las Vegas and was at the MGM Wet Republic pool yesterday...he cheated on you,' Wiltshire said.

She noted that another girl informed her of the infidelity and insisted she did not flirt with the man herself, 'but he was flirty with me and my friends.'

Wiltshire shared a video of the man, taken at the MGM Grand casino on March 9, adding that he flirted with her and her friends

'I went to test the waters 'cause I wanted to find out his Instagram so that I could DM you, and so I went over and I just said, like, hi, like where are you from, whatever, and he was super flirty,' Wiltshire continued.

'And I said, oh, are you the one getting married and he said, um, supposedly - something like that.'

She added that the man and his friends were wearing pink hats and she believed to have found his Instagram.

However, she declined to share the username, 'in case I get, like, sued.' 

Wiltshire urged other women to contact her if they suspected they'd been cheated on. She ended the video, but not before alluding that the groom's name rhymed with 'Cat Saddams.'

While the clip was met with a flood of support, including praise for being a 'girls' girl,' the influencer quickly encountered issues.

As online sleuths began hunting for the man, who many believed to be named Matt Adams, some netizens stumbled upon wedding registries.

Wiltshire shared her Instagram messaging history with another woman beseeching her to 'tell people to stop messaging us.'

The woman wrote that her fiancé was named Matt Adams 'but he has not been to Vegas & would never cheat.'

She added that she had to disable her wedding website after a flood of strangers RSVPed.

After alluding that the man's name 'rhymes with Cat Saddams,' netizens flocked to the wedding registries of men named Matt Adams, sparking controversy

She fended off commenters who insisted that the mystery groom-to-be did nothing wrong

'I'm a horrible person for trying to save this girl from a lifetime of misery?' Wiltshire demanded in response to one comment

Viewers were quick to point out that Wiltshire's actions were becoming more harmful than helpful.

'At this point you may be doing more damage than good. Put his IG out there and let it be,' one user remarked beneath the video.

'They should take legal measures against you. You knew very well what you were doing. It was all for the views,' another wrote.

The influencer received disparaging comments about her appearance and was even accused of cheating with the mystery groom. 

Wiltshire responded to one commenter in a follow up video, saying she had received scores of similar remarks, 'and they're all from girls.'

'You could have just kept your mouth shut or helped me look for her,' she ranted.

Another user deemed her 'a horrible person' and professed, 'What happens in Vegas stays in Vegas.'

'I'm a horrible person for trying to save this girl from a lifetime of misery?' Wiltshire asked incredulously.

'I cannot imagine how I would feel if I was scrolling through these comments and my man was commenting in support of a cheater.'

In another clip, she claimed that such comments came overwhelmingly from men. 

She pointed to one in particular reading, 'It's a bachelor party. You're supposed to cheat. If you don't you're a loser.'

'It is so disheartening and disgusting how expected it is for a man to cheat on a girl,' Wiltshire said.

'And the fact that so many people are just defending this man...it's not cool to openly support someone who's doing something just so morally wrong.'
