Arnold Schwarzenegger, 69, and his lookalike son Joseph Baena, 18, were spotted biking in Venice Beach this week.
Schwarzenegger and his mini-me had just been working out at Gold’s Gym before taking a spin, according to DailyMail.com.
The teen clearly takes after his dad, looking pumped up in a red tank top and black shorts.
Joseph is Arnold’s love child with former maid Mildred Patricia Baena.
Schwarzenegger and wife Maria Shriver split in 2011, at the same time his affair with Baena went public. Their divorce is not yet finalized.
Arnold and Maria wed in 1986 and have four children together; Katherine, 26, Christina, 25, Patrick, 22, and Christopher, 18.
