Nature is very odd and every once in a while it makes carbon copies of people. What's more interesting is when those copies are unrelated, doppelgangers if you will. Hollywood has many of their own doppelgangers, so if you ever thought, "Huh wasn't he/she in....?" and you were wrong, you aren't the only one. Here is a list of celebrity confusions that are basically sisters from another mister or brothers from another mother.

1. Matt Czuchry and Graham Rogers

If you watch Netflix and ABC, then you know who these two lovely men are. Both of these boys play troubled souls except while Quantico fans adore Rogers, the Gilmore Girls fandom hates Czuchry's character, Logan Huntzberger. If you don't, well, you should.

2. Kristin Stewart and Teresa Palmer

Palmer, who starred in The Sorcerer's Apprentice, has been mistaken for the Twilight star multiple times. On one occasion she even autographed Stewart's name for a fan because they were "so crazy excited."

3. Jaime Pressly and Margot Robbie

Which one is which? Even I can't tell.

4. Goldie Hawn and Anna Faris

It's like a time machine. Anna Faris was even set to star in Hawn's Academy Award Winner, Private Benjamin.

5. Kristin Chenoweth and Cameron Diaz

Now we have a spare. Yes, I realize that sounds awful.

6. Natalie Portman and Keira Knightley

Maybe Portman can keep Will Turner company since Knightley has opted out.

7. Amy Adams and Isla Fisher

Fisher and Adams are the most famous Hollywood doppelgangers. Last Christmas Fisher even photoshopped Adams's face on her Christmas cards and no one noticed!

8. Natasha Richardson and Emma Thompson

Another famous doppelganger couple! Thompson even went on to play Liam Neeson's (Richardson's husband) sister. Sadly, Richardson passed away in 2009.

9. Kendall Jenner and Jacinda Barrett

When I was watching Bridget Jones: The Edge of Reason I kept thinking "Why is Kendall Jenner in Bridget Jones?"
