News broke of Stewart's fling with her married "Snow White and The Huntsman" director Rupert Sanders on July 25, as incriminating photos hit the web. The "Twilight" saga star later issued a public apology to fans, family and Robert for her highly publicized "momentary indiscretion."

In the week since, the couple has reportedly vacated the Los Angeles home they once shared, with sources saying Robert and Kristen are no longer on speaking terms.
