A woman has gone viral on TikTok after revealing she faked her own wedding in a bid to get revenge on an ex-boyfriend.

Sarah Vilard, 24, lives in Frankfurt am Main, Germany, where she works as an investor and studies business management.

In 2019, she split from her ex-boyfriend, not named for privacy reasons, but rather than wallow in post-break-up blues, the young woman decided to get revenge in a very unique way.

She faked her own wedding.

Just three months after their split, Sarah pulled out all the stops for an elaborate photoshoot, even hiring an actor to pretend to be her groom.

The 'couple' were photographed celebrating their 'wedding' at the lavish Villa Kennedy in Frankfurt and Sarah even got her friends involved.

Sarah later shared a video of the big day on TikTok, leaving users impressed at the lengths she went to in a bid to show her ex what he's missing.

In the video, the 'bride' can be seen wearing a stunning white wedding dress as she poses with her 'groom' and a friend.

Despite the whole celebration being completely fake, it looks incredibly – with the pair appearing loved up and happy.

The video has been viewed 1.8 million times and received nearly 4,000 comments so far.

"This level of dedication is either completely psychotic or absolutely genius," one TikTok user wrote.

Another person encouraged: "Girl...what about the honeymoon? You have to go all the way."

"I personally see nothing wrong with this," one person commented.

Although not everyone was impressed, as one TikTok user added, "Lol, you’ve unlocked a new level of petty, congrats."

Another person revealed that they themselves had tied the knot – for real – pretty fast after splitting with their ex.

"I actually got married like five months after I left my toxic ex and it was honestly one of the best decisions I've made," they wrote.

Sarah's ex discovered the news of her so-called wedding on Instagram after she posted photos of her big day, and unsurprisingly, he was more than a little bit shocked.

"He found out through Instagram and texted me the next day and freaked out because he thought I was cheating on him while we were together," Sarah told Jam Press.

"That, of course, wasn't the case. But he came to my house and wanted to talk to me afterward. I wasn't interested."

Sarah was left feeling "satisfied" that her elaborate plan had worked and promptly blocked and deleted him from her social media and her life.

She said: "I blocked him everywhere and set my profile to private and removed the pictures.

"Yes, I am single now and super happy about it. I'm happy to be able to focus on myself."

Many people were shocked to discover that Sarah had spent so much money on the fake wedding, although she doesn't want to reveal the actual amount.

She added: "I think people think I'm crazy.

"But overall, I've had mostly good reactions and over 5,000 people following me.

"I had fun planning this little project with my friends."
