OMG IT'S OVER: Maria Shriver Files for Divorce

Maria Shriver is taking a stand today, as one of few political wives to say "eff you" to her cheating husband. After finding out two months ago that Arnold Schwarzenegger, her husband of 25 years, fathered a child with their long-time housekeeper, Shriver has filed for divorce.

People reports that she turned in the papers in an LA court today, citing irreconcilable differences. They add:

Shriver is seeking shared custody of their minor children, Patrick, 17, and Christopher, 13. The couple also have two daughters, Katherine, 21 and Christina, 19.

Since Shriver found out the truth from the former housekeeper, Mildred Baena, Shriver and Schwarzenegger have reportedly been living apart from one another. He took a trip to Austria, and she has been spotted strolling on the beach in Malibu and dining with Oprah.

Baena, for her part, has not spoken much to the media except for one tell-all interview with Hello! magazine.
