Cook? Nanny? Housekeeper? No details, but (a) she was married, and (b) the kid is at least 10 years old:
Former California Gov. Arnold Schwarzenegger and his wife, Maria Shriver, separated after she learned he had fathered a child more than a decade ago — before his first run for office — with a longtime member of their household staff. . . .
To protect their privacy, The Times is not publishing the former staffer’s name nor that of her child.
This kinda explains the divorce, eh?

UPDATE: The Sperminator.
