A woman (@joiederouen) on TikTok found out her boyfriend was cheating after finding a strange print on the passenger side.
JoJo, 21, posted a video as she sat in her boyfriend’s car.
As she sat in the passenger seat, she scanned over the front of the car, and then began to zoom in on the passenger visor mirror.
On the mirror, there was a collection of small circles from what appeared to be an Octobuddy phone accessory.
An Octobuddy is a phone case or sticker that can be put on the back of a phone.

It has suction cups that stick on flat surfaces and are often used by creators who film videos of themselves.
There was text over JoJo’s video that read: ‘Crazy because this is how I found out about the other girl.’
Her video has amassed over 11.4 million views and 672,700 likes.

Thousands of people commented on the shocking video and many shared their own stories of catching a cheating partner.
