America Ferrera and Amber Tamblyn double date! See more on and offscreen Hollywood BFFs.

America Ferrera and Amber Tamblyn are not shy about their close relationship. "She was one of three people to speak at my wedding. She's one of my best friends."

Tamblyn told Us Weekly how a double date normally goes down for the Sisterhood Of The Traveling Pants girls. "Usually America and I go out first, eating and catching up and talking about extensionalism and philosophy, and where we are in our lives. And that usually lasts about two hours, and then the dudes join up and then we talk about sports for 10 minutes. And then America and I go back to being in love with each other. They go off and do their own thing." That sounds like perfect best friend behavior to us. Who needs dudes when you have a BFFL?!
