1. Amy Adams & Isla Fisher
These two great actresses are always getting mixed up.

2. Katy Perry & Zooey Deschanel
Cutesy and quirky, you can never have too many people who look similar to these girls.

3. Javier Bardem & Jeffrey Dean Morgan
We all know Jeffrey Dean Morgan as Denny from Grey’s Anatomy (sob) but he is also known as Javier Bardem’s twin. Well, we think he is anyway.

4. Lea Michele & Idina Menzel
Idina played Lea’s mom on Glee unsurprisingly!
