Cohasset gal Kate Bosworth and boyfriend Michael Polish had front-row seats (next to photographer Mario Testino) at the Burberry show at London Fashion Week over the long weekend. Bosworth has been around fashion since she was a kid; her dad, Harold, used to be an executive at Hingham-based Talbots. In case you’re wondering, Polish directed Bosworth in the yet-to-be-released adaptation of Jack Kerouac’s “Big Sur,’’ in which she’ll star opposite Josh Lucas. Polish’s previous films include “The Astronaut Farmer.’’
