They may be some of the most famous faces in the world.
But these celebrities often suffer cases of mistaken identity.
From Katy Perry pretending to be Zooey Deschanel to get into clubs, to Liam Neeson signing autographs as Ralph Fiennes, many stars get confused for others.
Now, the Greek Golden Ratio of Beauty has been used to reveal exactly which celebrity doppelgangers look the most alike.
This mathematical equation was devised by the ancient Greeks to measure beauty.
The ratio can be applied to almost anything and was even used by Leonardo Da Vinci for the perfect human male body in his famous work, the Vitruvian Man.
According to the analysis, Dylan McDermott and David Schwimmer are the male stars who look most alike.
Meanwhile, Emma Mackey and Margot Robbie top the list for similarity amongst female celebrities.

The premise behind the Golden Ratio is that the closer the ratios of a face or body are to the number 1.618 (Phi), the more beautiful they become.
For the study, the team at Spin Genie applied the ratio to pairs of celebrity doppelgangers.
‘They measured the distance between features like the eyes, nose, mouth, and overall face length to give each one an overall facial proportions ratio,’ Spin Genie explained in a blog.
‘According to this mathematical concept of ideal proportions, the doppelgangers with the closest ratios look the most alike.’
