Kristen Stewart affair began last year and ended last week - Report

Kristen Stewart has already issued a public apology, and so has Rupert Sanders, but that's not stopping the media from digging up more details of their affair.

According to Leopold Ross, Sander's brother-in-law, the affair began during the last half of the filming of Snow White and the Huntsman and lasted until last week. Ouch.

Both Kristen and Rupert have said that it was a "momentary indiscretion" but Robert Pattinson knows what's up. He's already moved out.

From NY Daily News:

Though Kristen Stewart has called her fling with “Snow White and the Huntsman” director Rupert Sanders a “momentary indiscretion,” a relative of the British filmmaker claims the pair had been secretly seeing each other for months.

Leopold Ross, the brother of Sanders’ wife Liberty Ross, told the U.K.’s The People that he believes the 22-year-old actress became involved with the 41-year-old director during production of “Snow White” last year.

“It was from the last half of filming and all through post-production, clear into last week,” Leopold Ross told the publication.

He noted the anger felt by his sister, who uprooted her life and her two young children’s lives in England to move to Hollywood in an attempt to help further Sanders’ career.
