Fred is from Brazil. Fred's language of origin is, therefore, Portuguese (I know, I was confused to learn that he doesn't speak Brazilian, too). Fred also speaks a bit of Spanish - and less English - but whenever he gets interview requests, folks ask him to speak in either of those two languages and not his native Portuguese.
Below is a video from a recent interview Fred did on camera for us, in Spanish... as you'll see, he stumbles over the words first, but then gets thrown off by our videographer's cell phone going off. Really, this is only funny because Fred has such an infectious laugh!
