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 became engulfed in a firestorm of controversy after reporting that a man cheated on his bride-to-be during his bachelor party in Vegas.

Tiana Wiltshire, a personal trainer and nutrition coach, uploaded a TikTok video on Sunday to share her findings. The clip quickly went viral and had been viewed nearly 24 million times by Thursday evening.

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 a 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 that she wasn’t flirting with the guy herself, “but he was flirting with me and my friends.”

“I was going to test the waters because I wanted to find out his Instagram so I could DM you, and so I went over there and just said, hey, like where are you from, whatever, and he was super flirty,” she continued Wiltshire.

“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 that she thought she found his Instagram.

However, she declined to share the username, “in case I get sued.”

Wiltshire urged other women to contact her if they suspected they had been cheated on. She ended the video, but not before hinting that the groom’s name rhymed with “Cat Saddams.”

While the clip received a lot of support, including praise for being a “girly girl,” the influencer quickly ran into trouble.

As online sleuths hunted for the man, who many thought was named Matt Adams, some Internet users stumbled across marriage records.

Wiltshire shared her messaging history on Instagram with another woman, imploring her to “tell people to stop messaging.”

The woman wrote that her fiancé’s name was Matt Adams “but he hasn’t been to Vegas and would never cheat.”

She added that she had to take down her wedding website after a flood of strangers signed up.

“I’m a terrible person for trying to save this girl from a life of misery?” Wiltshire asked in response to one comment

Viewers were quick to point out that Wiltshire’s actions ended up being harmful rather than helpful.

“Right now you might be doing more damage than good. Put his IG there and let it be there,” one user commented under the video.

“They should take legal action against you. You knew very well what you were doing. It was all for the opinions,” wrote another.

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

Wiltshire responded to a commenter in a follow-up video, saying she had received dozens of similar comments, “and they’re all from girls.”

“You could have just kept your mouth shut or helped me find her,” she ranted.

Another user called her “a horrible person” and claimed, “What happens in Vegas stays in Vegas.”

“I’m a terrible person for trying to save this girl from a life of misery?” Wiltshire asked incredulously.

“I can’t imagine how I would feel if I was scrolling through these comments and my husband commented in support of a cheater.”

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

She pointed to a specific text: “It’s a bachelor party. You’re supposed to cheat. If you don’t, you’re a loser.’

“It’s so disheartening and disgusting how expected it is for a guy to cheat on a girl,” Wiltshire said.

“And the fact that so many people are just defending this guy… it’s not cool to openly support someone who is doing something that is morally wrong.”
