Patrick wished his father a happy birthday by posting an image with the family. The photo shows Arnold holding a cake with a humorous photo of himself on it.

“The cake,” Patrick wrote with two laughing emojis. “Happy Birthday big guy @schwarzenegger.” Patrick ended the caption with a birthday cake emoji and a celebratory emoji.

2019 has been a big year for Arnold. Not only is he returning in the new Terminator film, but his daughter, Katherine Schwarzenegger married Avengers: Endgame star Chris Pratt in June.

Baena also graduated from Pepperdine University in April.

In May, Patrick was on the cover of GQ Germany with his father. There, they spoke about their close relationship.

“My vision was to create great kids. What I’m proud of is that I could kind of show him the way and he knew that he has all the help in the world from me all the time but that he had to do the work also,” said Arnold.

“My dad has always taught us kids… follow your passion, what you love. And if you follow those things then ultimately you’re going to be successful,” Patrick said of his father.
