A fourth woman claiming to have had an affair with Sandra Bullock's husband Jesse James is keeping quiet.

"I can confirm that she has decided not to tell her story," attorney Gloria Allred said Monday. "I have no other comment."

Last week, Allred said the unnamed woman -- described as a "beautiful model and businesswoman" -- had a three-year affair with James, 40, and possessed "hundreds of texts, emails, and photos." Allred said James had "strong feelings" for the woman.

Still no sighting of Bullock, 45, who has been M.I.A. since the scandal broke, though blogs are abuzz that she is hiding out at her home in the Hollywood Hills.

"She feels embarrassed to show her face after giving that Oscar speech," a source tells the new Us Weekly (on newsstands now). "He ruined her life."
