Arnold Schwarzenegger appears to have grown quite close to his youngest son Joseph Baena over the years, with the pair sharing interests such as bodybuilding and acting.
The actor, 75, fathered his son, now 25, with his family's housekeeper Mildred Baena, now 62, while married to Maria Shriver, now 67, who's the mother of his other kids.
Joseph was largely kept out of the spotlight until recent years, with him now pursuing opportunities in the public eye - like having competed on Dancing with the Stars last year.
