Orlando Bloom is reportedly still dating his on-off girlfriend, actress Kate Bosworth. According to the American actress's sister, Bloom, 28, is still involved with the Blue Crush and Beyond the Sea star, even though he was recently seen cuddling up to old flame Sienna Miller. Bloom and Bosworth had announced last January that they were ending their two-year relationship, but last month, Bloom visited the set of Bosworth's film Superman Returns and the pair rekindled their romance. Reports that Bloom is now involved with actress Sienna Miller, were sparked when they were seen together at a charity polo match. Miller recently ended her engagment to Jude Law, after it was revealed that he had been cheating on her with the nanny of one of his children. Regardless of the rumours, Bloom's sister says that Bosworth is his one love, and that his relationship with Miller is purely platonic. |
