People Can't Believe They Aren't Twins - They're Sisters, But Which One Is Cameron Diaz?

Cameron Diaz is one of the more recognizable faces in Hollywood, so it's no wonder fans are surprised when they see double in this picture.

The 44-year-old American actress is well known for her role in 1998's There's Something About Mary, as well as her voice acting the role of Fiona in the Shrek series.

Before she was an actress, Diaz modeled for Elite Model management and worked on contracts for Calvin Klein, Levi's and Coca-Cola. You'd think that there couldn't possibly be another woman in the world like her... and yet:

You're not seeing double! Nor is it two pictures of Cameron! This is actually a beautiful picture of Cameron (left) and her older sister Chimene Diaz. The women were born two years apart - but boy does that family have some strong genes!

We've seen Cameron with different hair colors before, which is probably why it took fans a second to figure out who was who in the photo!

But do you see the difference now?

Again, Cameron (left) and her sister Chimene (Right). Same eyes, same smile - two stunning women!  Could you tell the difference at first?
