Arnold Schwarzenegger has a grown-up son who looks exactly like his father in last shared photo

Arnold Schwarzenegger's 21-year-old son, Joseph Baena, posted a photograph of himself flexing at the gym recently. Without a doubt, he is the spitting image of his famous father.

In the Instagram photo, Joseph, who is the child of Schwarzenegger with an employee in their household, Mildred Patricia "Patty" Baena, is seen exposing his muscles in nothing but a pair of black shorts and sneakers. "Just a lil thicc," he captioned the image.

Joseph regularly shares his fitness regimen and progress on Instagram, which frequently calls attention to their similar looks.

According to People, Joseph recreated his father's iconic photo taken in 1975. The "Commando" actor, 71, posed for the picture after he won Mr. Olympia for the sixth straight time.

Joseph's followers noticed the likenesses between the father-son duo and remarked on how much he looked like Schwarzenegger.

This isn't the first time that his followers have marveled over the pair’s resemblance.

Joseph regularly shares his fitness regimen and progress on Instagram, which frequently calls attention to their similar looks.

In November, he posted a video of himself flaunting his massive arm muscles. Again, fans commented he seemed to resemble his legendary dad.

“It’s only the beginning," Joseph wrote.

It looks like Schwarzenegger likes to assist his child with his workouts, as well. On Joseph's birthday in 2017, the actor posted a picture of them hitting the gym together.

"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," Schwarzenegger captioned the image.

Another child of Schwarzenegger who appeared to be interested in following his footsteps is his oldest son, Patrick Schwarzenegger, with ex-wife Maria Shriver.

Patrick, 24, made his debut as a romantic leading man in the movie, "Midnight Sun."

He had small roles in several films, including "Stuck in Love," "Grown Ups 2," and "Scouts Guide to the Zombie Apocalypse."
