Samantha Barks, David Gandy split

London: `Les Miserables` actress Samantha Barks and David Gandy have reportedly split up for the second time after their demanding careers put a strain on their relationship.

The actress and the 33-year-old model, who broke up briefly in July, have called time on their relationship for the second time, reported Daily Mirror. "Both Samantha and David are in high demand professionally and are really busy with their careers. David`s modelling is taking him all over the world and Samantha is the same - with regular gigs in America and Australia," a source said. "With such packed schedules they were both finding it increasingly difficult to see each other." Just four months ago, Gandy, who began dating Barks in May, claimed he was single after he jetted off to New York for a job while the brunette beauty was pursuing her dreams in Los Angeles. But the pair appeared to patch things up almost immediately after they were spotted together at the Virgin Media V Festival in August. PTI
