“She was thinking of including Liberty, Rupert and the kids in her public apology — but Kristen was so desperate to save her relationship with Rob she decided to concentrate on that first,” a source tells the site. “Kristen feels she made a terribly naïve mistake and will do anything to make amends. The fact that Liberty and Rupert have two kids has now dawned on her and she feels awful for what she did.”
Liberty has been married to 41-year-old Snow White and the Huntsman director Rupert Sanders for seven years, and the couple has three children.
Yesterday, Kristen released a statement in which she admitted to the fling and expressed her deepest regrets for hurting Rob, her Twilight co-star/boyfriend of three years. “This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry,” she said.
