Like Cameron Diaz, Keira Knightley is a different person when she smiles. Unlike Victoria Beckham, it ain’t a good thing. With Cam, it’s because of the wide Joker mouth – adds a weird caricature-ishness to her features, frightening small children in the process. For Keira it’s the teeth. Flying razors grown haphazardly in all directions, made even more alarming by the protrusion of her wickedly square and decidedly prominent jaw. Needless to say, when you take away the makeup, it’s much worse. WITH makeup however, in both cases, the improvement is impressive. Here’s Keira last week minus embellishment, Keira at the weekend all dolled up and lovely and NOT smiling. Makes a huge difference, don’t you think? PS. Heard from British sources that K is NOT looking forward to working with Lilo in the Spring. Apparently Lindsay blew her off when she was in town a few weeks ago. Consequently, Keira plans to return the favour, rumour has it she won"t return emails and is trying to win favour with the crew before Lindsay arrives - it"s all about who has better lighting, savvy? Can"t wait til these 2 start shooting together. Something tells me Keira Knightley can scratch back HARD. Source
