Oh lordy. Kristen Stewart shocked the world when she came clean and admitted, via a public and very grovelling statement, that she had cheated on Robert Pattinson with Snow White and the Huntsman director Rupert Sanders. News first broke that the 22-year-old had cheated on Rob with married Sanders, 41, after photographs of the pair kissing were published. Sanders is married to Liberty Ross, 33, who starred alongside Kristen in the Snow White film, and they have two small children together.
