Life goes on for Maria Shriver.

Shriver, still noticably not wearing her wedding ring, was spotted leaving a Whole Foods grocery store in Brentwood, California on Tuesday with her youngest son Christopher.

While Shriver, 55, technically remains married to actor/politician Arnold Schwarzenegger, 63, the former TV journalist has retained L.A. powerhouse divorce attorney Laura Wasser after revelations he fathered a child with his long-time housekeeper Mildred “Patty” Baena.
