We totally understand how easy it is to get some people confused. Check out this gallery of celebrity siblings who are actually the same person.
Pippa and Kate Middleton

Pippa Middleton might have the better…ASSETS…but she and sister Kate Middleton definitely got the same amazing smile.
Kylie and Kendall Jenner
If Kendall Jenner ever needs a sick day from all that Instagram selfie-ing she does, she can just let sister Kylie pick up the slack. But then who would post Kylie’s selfies to Instagram?
Angelina Jolie and James Haven
Once upon a time, siblings Angelina Jolie and James Haven frequently kissed for the paparazzi. So it was basically like they were kissing themselves in the mirror.
Casey and Ben Affleck
Casey Affleck may not be as well known as big brother Ben Affleck, but it’s not because he didn’t get his brother’s looks!
Elle and Dakota Fanning
Child star Dakota Fanning stepped aside to give little sister Elle Fanning the spotlight, but since the two look so similar it’s almost like she never left.
Khloe and Kim Kardashian
Which Kardashian sister is which? (That’s Khloe on the left and Kim K on the right!)
Paris and Nicky Hilton
Paris Hilton gets paid to walk the red carpet. She could totally double book herself and send sister Nicky Hilton in her place.
Solange Knowles and Beyonce
Seeing Solange and Beyonce side by side like this, are we SURE it was Solange who went to town on Jay Z and not Beyonce?
Christian and Neve Campbell
Christian and Neve Campbell look so much alike we want to SCREAM!
Haylie and Hilary Duff
Hmmm, let’s see…did Hilary Duff play Cinderella or was that sister Haylie Duff? We can’t tell!
The Baldwin Brothers
Ah! A quartet!! There are FOUR Baldwin brothers! Clockwise from left to right: Daniel, Billy, Stephen, and Alec. Anger issues and drug addictions abound for this bunch.
Jamie Lynn and Britney Spears
Jamie Lynn Spears and sister Britney Spears should become a musical duo.
Emily and Zooey Deschanel
Okay, Zooey Deschanel MIGHT look more like Katy Perry than her sister Emily Deschanel. And she probably acts more like Katy, too.
Maggie and Jake Gyllenhaal
If we hadn’t seen Maggie Gyllenhaal breastfeeding her tot, we’d definitely be convinced she and brother Jake Gyllenhaal are the same person.
Alex and Emma Watson
If Harry Potter directors had decided to take creative license and make Hermione Granger a boy, Alex Watson could’ve played the part for sister Emma Watson.
Ashlee and Jessica Simpson
Another dynamic sister duo, Jessica and Ashlee Simpson definitely look like family!
Mary Kate and Ashley Olsen
Mary Kate and Ashley Olsen have definitely been fooling us all this whole time.
