Everyone has that one star that they kind of, sort of look like, but these 15 people can't leave the house without being mistaken for a celebrity:
1. Barack Obama
Jose Oliveira says the at least 15 times a day somebody stops him and asks to take a photo with the former president, but insists that "Barack Obama looks like me."
2. Taylor Swift
3. Katy Perry
Copying the singer's signature hairstyles and iconic outfits, it's no surprise that Francesca Brown works as a Katy Perry impersonator.
4. Prince William and Kate Middleton
Heidi Agan quit her job as a waitress after being repeatedly compared to the princess, and often appears alongside Simon Watkinson. The model has been dubbed "the world's best Prince William," which seems like an insult to the man himself.
How about some '90s TV star lookalikes?
5. Jason Alexander
Remember George from Seinfeld? This little girl - who would probably prefer to remain anonymous - is a dead ringer for the TV star.
6. Matthew Perry
Could Reddit user johnsuros BE any more like Chandler Bing? He's the spitting image of the Friends star during the height of his career, and says people constantly ask if they know him from somewhere.
7. Harry Styles
Sure, this teenager looks just like the One Direction boy band member who recently appeared in the movie Dunkirk, but can he sing like him? Probably not.
8. Benedict Cumberbatch
With his alien looks you wouldn't expect anyone else to resemble Benedict Cumberbatch, but teenage model Tyler Mitchell has used their striking resemblance to jump-start his career.
9. Ariana Grande
Side-by-side these 2 really are hard to tell apart. Jacky Vasquez plays up her resemblance to the Dangerous Woman singer by sporting her famous headband and ponytail combo often.
10. Ed Sheeran
Even this singer was "gobsmacked" by how much he and Ty Jones look alike when they met in person. Jones works as a Sheeran impersonator (of course), but lip syncs to the ginger singer's tunes.
11. Angelina Jolie
Scottish woman Chelsea Marr admits to getting lip fillers and a nose job, but insists it's just a coincidence that the procedures made her look like Angelina Jolie's twin. Believe it or not, she looks like a mirror image of the actress.
Sometimes, doppelgangers actually have more talent than the people they look like.
12. Justin Bieber
Singer Dani Shay was a contestant on America's Got Talent, and picked Bieber's "Baby" as her audition song, so she knew that there would be comparisons between her and the singer. But now that Bieber is growing in his facial hair they're easier to tell apart.
13. Emma Watson
Since she was a little girl, people have been telling Megan Flockhart that she could be related to the Harry Potter star, and when she dresses up like her "idol" at conventions they're hard to tell apart.
14. Kim Kardashian
Lucky lookalike Kamilla Osman got to meet this reality star and model in the flesh, and of course they took a selfie to mark the occasion. Osman is a fashion blogger, so they also share a sense of style.
15. Ryan Gosling
Lots of guys wish they looked like the Notebook star, but only Robert McKinnon really does. Dating sites have even deleted McKinnon's accounts after accusing him of impersonating Gosling.
