A woman has been praised for her "FBI levels" of investigation after sharing her hilariously simple method to discover if your significant other has been unfaithful.
TikTok user @Andrea.Lopez44 boasts more than 1.7 million followers on the video sharing platform and recently uploaded a clip captioned: "How to find out if your man is cheating."
It's racked up more than 12 million views as she explained: "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."
Andrea then uses the lint roller over the floor in her boyfriend's bedroom, picking up plenty of dust along with what appeared to be a few stray red hairs that were impossible to spot before.

She then jokingly asks" "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."
Someone else wrote: "Men we gotta throw away our carpets NOW", leaving Andrea to reply: "Wood floors all 2021."
A third added: "Imagine getting accused because you have a dog that sheds."
And another found a flaw in the plan, commenting: "Like men know to clean their carpet. That could be the previous owner's hair."
