It’s ironic that the son of Arnold Schwarzenegger who turned out to be the most like his father is Joseph Baena, the son he had with his housekeeper. Of course, that revelation broke up Arnold’s marriage to Maria Shriver, but he doesn’t hold it against the boy or his mom. According to TMZ, Arnold does have a relationship with the 16 year old and has noticed that husky Joseph has inherited his father’s physique. He might be another Mr Olympia in the making! Arnold started working out at 16, and he’s delighted at the prospect of mentoring his own bodybuilder son, so he’s providing the gym equipment and encouragement to get Joseph started.
