A photograph of six girls posing for a photo on the beach has gone viral for a very amusing reason, but can you spot what it is?

Read below to find the answer!

Leaning toward the camera the mates appear to have all adopted a similar pose and are wearing matching black sunglasses. But those with a keen eye may be able to spot that the photograph has been tampered with. A social media user has photoshopped the face of a man in the background onto the six faces of the women. Once you’re aware of the edit to the picture it can seem blindingly obvious however plenty of Instagram users admit that they were stumped.
