Shoppers watched on in disbelief as a bride-to-be stormed into her fiancé's place of work demanding he marries her "right now" or "it's over".
The furious woman, who was caught on film, could be seen making her way into a Target store in Las Vegas, US, as she tried to locate her partner.
The moment she found him, she began to make her demands even giving him an ultimatum that if he doesn't marry her on the spot, their relationship is finished.
"You put this ring on my finger two years ago and it's time to do it or get out," she told her fiancé who was in the middle of restocking shelves.
She then turns her attention to those watching, including baffled shopper Ashley, who posted the clip to TikTok, under the handle @boymom_ashley.
"Hi guys, I'm just finally making him commit," the bride told the group of onlookers.
"You know, like were getting married now, or like it's over."
Ashley can be heard saying "woo-hoo" as she continues to film the bizarre fiasco.
The bride then turns her attention back to her stunned fiancé who asks if they can "talk about it", to which she responds, "Yes, we can talk about this outside."
As they walk off, the unnamed bride stares into Ashley's camera and laughs as she says, "I'm shaking".
"Could someone have told me about it?" her fiancé then asks.
It is unclear whether the bride and her fiancé tied the knot, with no third clip showing what happened after the in-store ambush.
However, the two-part clip attracted plenty of attention, with more than half a million views both on TikTok and Reddit.
"The best part of my week watching this woman hunt her man down that works at Target," Ashley captioned the videos, alongside the hashtag "bridezilla".
