A woman has gone viral after suggesting a quick way to find out if your partner has cheated.
Taking to the popular Tik Tok app, Andrea Lopez was deemed to be worthy of the FBI after she shared the quick hack.
The short video quickly racked up millions of views and required only a lint roller.
According to Lopez, the sticky hair brush is the ideal way to know if something is going on behind your back, and was praised hundreds of times for her genius.
Speaking to her followers, she said:
"Ladies, if you want to find out if your man is cheating on you, get yourself one of these and roll it all over their carpet like this."
According to the Daily Mirror, Lopez then rolled the lint roller all over the floor, to see what hairs it would pick up.
Unfortunately, the roller picked up quite a few long ginger hairs, which are a very different color to her jet black locks.
Jokingly worrying about the find, she said: "What the f***?" as she flipped the camera around to show her dark hair, adding: "My hair is black."
Viewers flooded the post with thousands of comments, as one replied to say: "I guess everyone is single after this video huh?"
A second wrote: "Okay but this is the FBI level."
A third asked: "What if the other girl have black hair?", only for another to reply suggesting they take their investigation to the next step, advising: "DNA test kit."
And the video proved to be a good learning tool for cheaters too, as one said: "Clean the floor when you have a girl over. Got it."
