Los Angeles (CNN) -- Maria Shriver and her children are "circling the wagons and are working through" the family crisis brought on by the revelation that Arnold Schwarzenegger fathered a child more than 10 years ago outside his marriage, a source close to Shriver told CNN Tuesday. The former California governor is "way on the outside of the circle" and "rambling around" their huge house with none of his family around, said the source, who asked not to be identified because of the sensitivity of the matter. The revelation, published first by the Los Angeles Times, came about a week after Schwarzenegger and his wife of 25 years announced that they were "amicably separating."
