“Happy birthday @projoe2! I love watching your progress with your training, your work, and in every part of your life,” he captioned.
“I can't wait to see what’s coming next. I love you!”
Baena is the son the Terminator star had with his former housekeeper, Mildred Baena, who had worked for the Schwarzeneggers for 20 years.
He was born in 1997, while Baena was still working for the family, Schwarzenegger confirming his paternity some years later in 2011.
The affair ended Schwarzenegger's marriage to Maria Shriver, niece of former president John F. Kennedy and senators Robert F. Kennedy and Ted Kennedy.
Schwarzenegger and Baena have had a close relationship every since, with Arnie showing particular interest in Baena's enthusiasm for body building.
The pair are also often seen out and about, riding their bikes in Los Angeles.
The True Lies actor also has children Patrick, 26, Christopher, 23, Christina, 28, and 30-year-old Katherine Schwarzenegger Pratt, who married actor Chris Pratt last year.
