Actor Orlando Bloom and his on-again, off-again girlfriend of nearly four years, Superman Returns Kate Bosworth, have split, Entertainment Tonight reports. Sources close to the pair tell ET that the Pirates of the Caribbean star and the 23-year-old actress have decided to go their separate ways. (The couple's rep could not be reached for comment.)

Bloom, 29, is currently on location in Southern California shooting Pirates of the Caribbean: At Worlds End. He recently attended the Teen Choice Awards on August 20 solo, where he accepted the surfboard award for 'Choice Hottie.'

However, there could be some awkward moments in the former couple's future. This month, they're set to start filming Seasons of Dust, a Depression-era drama about a young woman (Bosworth) whose uncle commits suicide, forcing her on the lam with a dashing thief (Bloom).
