Newly single Kate Bosworth and director Michael Polish shared an affectionate night at the Coldplay concert, sponsored by Samsung, at the Los Angeles Tennis Center at UCLA. The two giggled together as Polish wrapped an arm around Bosworth's waist and kissed her on the cheek. They also snuck in even more kisses during the show and looked "totally adorable" together, an onlooker says. Meanwhile, lead singer Chris Martin's wife Gwyneth Paltrow stayed under the radar, hanging backstage during the concert.
