Since news exploded that Kristen Stewart cheated on Robert Pattinson with Snow White and the Huntsman director, Rupert Sanders, rumors of the exact details of how it all went down have been flying. First, reports were that Stewart, who publicly apologized for her affair, had only kissed Sanders. Then reports insinuated something much more serious had transpired when U-Haul trucks were spotted moving Stewart's belongings out of their $6 million home in L.A. 

Now rumor has it that Stewart and Sanders had been sleeping together for six months. Exactly who is the source of this rumor? Leopold Ross, brother of scorned wife Liberty Ross.

"It was from the last half of filming [Snow White and the Huntsman] and all through post production, clear into last week," Leopold Ross told UK's The People. 

No one really knows how long the affair lasted, or what exactly went down, but Leopold's testimony isn't so far-fetched given his closeness to Sanders. Surely this raises the smash probability to the next level.
