The 55-year-old author - who was married to the 'Terminator' actor for 25 years and has four children, Katherine, 21, Christina, 19, Patrick, 17, and Christopher, 13, with him - is attempting to "rebuild" her life after Arnold admitted paternity of the child, whose mother was a member of their household staff for more than 20 years.
In a statement, she said: "This is a painful and heartbreaking time. As a mother, my concern is for the children. I ask for compassion, respect and privacy as my children and I try to rebuild our lives and heal. I will have no further comment."
Arnold - the former Governor of California - previously explained he "takes full responsibility" for the anguish he has caused his Maria, who has since moved out of the former couple's marital home, and their children.
He said: "I understand and deserve the feelings of anger and disappointment among my friends and family. There are no excuses and I take full responsibility for the hurt I have caused.
"I am truly sorry."
