Now, an insider tells Radar Online, the actress is prepared to address Sanders' wife directly. She is apparently writing a note to Liberty Ross.
"Kristen didn’t feel it was appropriate to issue a public apology to Liberty once the story of her affair with Rupert broke," the source says. “Instead, she’s going to do the decent thing and write Liberty a private letter expressing her deepest regret for her actions."
The mole goes on to say that Stewart only wanted to mention Pattinson in her initial statement because she's "desperate to save" that relationship.
But she feels "awful" for getting in between a man, a wife and his two children.
For whatever it's worth to either Ross or Pattinson, a reliable website claims Stewart and Sanders did NOT have sex.
