Like father, like son!
Arnold Schwarzenegger is known for his days as a bodybuilder, and it’s safe to say that his kids inherited their dad’s love for fitness.
Maria Shriver’s ex took to Instagram on October 2 to wish his son Joseph Baena a 20th happy birthday.
And the adorable duo spent the day doing what they love most, working out in the gym!
The proud papa penned, “Happy birthday Joseph! You’re a fantastic son and a great training partner.”
“You get stronger and smarter every year and I’m so proud of you. I love you.”
Joseph Baena is Arnold’s love child with his former housekeeper Mildred Patricia Baena.
The Terminator actor had previously admitted to having an affair with her while he was still married to now ex-wife Maria Shriver — which is what ultimately led to their divorce.
Maria and Arnie have four kids together, their youngest son Christopher Schwarzenegger, who was born just five days before his half-brother along with Patrick Schwarzenegger, 24, Christina Schwarzenegger, 26, and 27-year-old **Katherine Schwarzenegger.
Arnold and Maria tied the knot in 1986 but they announced their split in 2011, and even though it’s been six years since they separated, the estranged couple has yet to finalise their divorce.
Arnold, who served two terms as the 38th Governor of California, opened up about the affair.
“Without any doubt. Not only failure, but you feel like, ‘I’m to blame for it. It was me that screwed up,'” the 70-year-old said in a 2015 interview with Howard Stern.
But even though he admitted that cheating on his wife was a big mistake, it didn’t stop him from being a good father to his son Joseph and the Schwarzeneggers have welcomed him into the family.
“[Joseph is] terrific and he totally understands the situation. So, it all has worked out… It’s a very tough situation for him,” Arnold said at the time.
“It’s a very tough situation for my kids, very tough situation for my family. It was tough for everybody. But it has happened and now we have to figure it out, right?”
