Arnold Schwarzenegger Ex-Factor: Mother's Day Edition

5/14/2012 6:00 AM PDT

Arnold Schwarzenegger spent Mother's Day with the mother of most of his children ... showing up at Maria Shriver's new Brentwood home yesterday.

Our sources say the day went well, but as for reconciliation ... even though Maria has gone back and forth on it, the divorce is still all systems go.

Arnold also spent Saturday with the fam ... showing up at his daughter's graduation from USC sporting a new goatee.
