When I first saw the photographer's caption about Scarlett Johansson going incognito at LAX, I was like "wow she's really done a good job", but upon closer inspection I realised that the person I first thought was Scarlett was indeed a mere civilian and she was in fact the person with the very recognisable lips hiding under a wooly beanie. Considering she's meant to be an actress she hasn't really gone out of her way to make sure she wasn't recognised. Personally if that was me and I really didn't want to be seen, I'd travel Michael Jackson stylee and wear beards, wigs and a burka. Pictures: London Entertainment / Splash
