Joseph Baena is definitely his famous father's son.
Arnold Schwarzenegger and the 18-year-old college student looked nearly identical as they rode bikes through Venice, California, on Wednesday afternoon. The duo were all smiles as they peddled along in their nearly matching shorts and T-shirts.

Prior to their father-son ride along, Baena and Schwarzenegger were spotted at Gold's Gym. These gym trips appear to be a common occurrence for the two, as they were also seen working out together in April.
Schwarzenegger fathered Baena with his former housekeeper, Mildred Baena. The 68-year-old action star has four additional children with estranged wife, Maria Shriver -- 26-year-old Katherine, 24-year-old Christina, 22-year-old Patrick, and 18-year-old Christopher.
In May, Baena -- who is majoring in business at Pepperdine University -- revealed just how much he looks like his father when he was spotted tossing a football around shirtless on the beach in Malibu.
