He raised him well! Arnold Schwarzenegger was all smiles as he posed with his youngest son, Joseph Baena, who was graduating from California’s Pepperdine University.

“Congratulations Joseph!,” the 71-year-old captioned a photo of he and his 21-year-son hand-in-hand. “Four years of hard work studying business at Pepperdine and today is your big day! You have earned all of the celebration and I’m so proud of you. I love you!” Take a look at the post below!

“Looks exactly like a young Arnold,” one fan commented on the post. “Congratulations to your son. You are a legend,” another added. Joseph took to Instagram as well to share numerous photos of his day, including one of he and his mother, Mildred Baena, together.

“Some of the best times of my life are because of this school and the people in these pictures,” the action star’s son captioned the photos. “I am so incredibly grateful to have the privilege to study at and graduate from such a beautiful and high caliber school. I now have my degree in business administration and with that, I believe this is only the beginning of a new road. Let’s see where it takes us!”

The True Lies star welcomed Joseph in 1997 with Mildred, his former housekeeper whom he had an affair with. Arnold shares four other kids — Katherine, 29, Christina, 27, Patrick, 25, and Christopher, 21 — with his now ex-wife, Maria Shriver. The pair split in 2011 after being married 25 years.

The fitness legend once sat down with Howard Stern to not only discuss the end of his marriage but the effect it had on Joseph and his other children.

“[Joseph is] terrific and he totally understands the situation,” Arnold said at the time. “So, it all has worked out … It’s a very tough situation for him. 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?”

We’re just glad Arnold gets to spend as much time as he wants with his youngest son!
