A source tells ET that Maria Shriver will likely be filing for divorce from estranged husband Arnold Schwarzenegger by the end of the week.
The couple announced that they were separating after 25 years of marriage on May 9, and in even more shocking news, Arnold later admitted to fathering an illegitimate child during his marriage to Maria. The woman who is allegedly the mother of Arnold Schwarzenegger's love child, Mildred "Patty" Baena, was named by a joint investigation by Radar Online and Star last May 17th. She worked as a housekeeper for the Schwarzenegger family for 20 years before reportedly retiring in January.
Maria and Arnold have four children together: Katherine, Christina, Patrick and Christopher.
