Kristen Stewart called her fling with Rupert Sanders a 'momentary indiscretion' but now relatives of the British director have claimed that the pair were seeing each other for months.
Sanders' brother-in-law, Leopold Ross, has said he believes Kristen and Rupert became involved with each other while they were filming Snow White and the Huntsman.
Model Liberty Ross' brother told of how his sister made 'sacrifices' for Rupert and that she was unhappy in their marriage for a while.
Speaking to The People, Leopold told that Kristen's affair with the 41-year-old director began during the second half of filming for the blockbuster movie, he explained: 'It was from the last half of filming and all through post-production, clear into last week.'
