13 Celebrities who always get mistaken for each other

It's weird enough when someone tells you that you look exactly like their cousin's housemate's girlfriend, and oddly flattering when a person tells you that so-and-so from Hollywood is your doppelgänger. But what's even stranger is when you're watching a movie at home and you and your bestie can't agree on the name of the actress on screen – one of you swears it's Isla Fisher while the other insists it's Amy Adams.

Given that a lot of stars are born into the industry from already famous parents, there are many lookalikes between mothers and daughters (think Goldie Hawn and Kate Hudson or Reese Witherspoon and her daughter Ava). But strangely enough, there are a lot of celebrities who aren't blood-related that could still pass as twins. Or at the very least body doubles, which would come in handy for film-related work, I suppose.

Celebrity lookalikes are surprisingly common, so here are 13 pairs of female A-listers who look freakishly similar.

See what I mean? They all look so similar! I never would've said that Zooey Deschanel and Katy Perry or Bella Hadid and Jennifer Lawrence look the same, but when seeing them side-by-side, there's no doubt about it. So if anyone's ever writing a movie that requires twins, there seem to be plenty of celebs who could play alongside each other to fit the part.
