Maria Shriver has filed for divorce nearly two months after the revelation that her husband, actor and former Governor of California Arnold Schwarzenegger, had carried out an extra-marital affair and fathered a child outside their marriage 14 years ago.

TMZ reports that Shriver cited irreconcilable differences in her California state filing, and has asked for custody of their two minor children, 17-year old Patrick Schwarzenegger and 13-year old Christopher.

Arnold Schwarzenegger, who served two terms in Sacramento between 2003-2011, fathered a son with household staffer Mildred Patti Baena. Shriver and Schwarzenegger announced their separation on May 9th.

The pair was married for 25 years and had four children together.

"This is a painful and heartbreaking time," Shriver said at the time of the first announcement. "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."
