Arnold Schwarzenegger and his wife of 25 years, Maria Shriver, haven't formally filed for divorce yet, and for good reason. Friends say Arnold still thinks he has a shot at winning Maria back.

"He knows he has made terrible mistakes in his past but isn't prepared to lose the greatest woman in his life," a friend of Arnold tells me. "This has nothing to do with money or the children, he misses her terribly and will do whatever it takes to win her back. Even begging."
