If Maria Shriver only knew, she probably wouldn't have been smiling.
We've obtained another photo, this time of Shriver and her former housekeeper Mildred Patricia Baena, before anyone had any idea they had so much in common. (They were both pregnant -- at the same time -- by Arnold Schwarzenegger.)
Also in the pic is Maria's brother, activist Anthony Kennedy Shriver.
Baena worked for the power couple at their mansion in the posh Brentwood neighborhood of Los Angeles for two decades.
And don't forget, it was RadarOnline.com and Star magazine’s joint investigation that revealed Baena, 50, as the mother of the teen son that the 63-year-old Kindergarten Cop star fathered out-of-wedlock.
