Fans of Patrick Schwarzenegger appear to wonder if he has “any relation to Arnold,” claimed the ‘Gen V’ actor.

People are still startled to learn that Patrick Schwarzenegger is Arnold Schwarzenegger’s son

“It’s really funny to me when people ask if I have any relation to Arnold when they see my last name,” the Terminator actor’s 30-year-old son wrote on X on June 27.

Patrick, who plays superhuman Golden Boy in The Boys’ spinoff Gen V, was responding to an X user’s realization that the two Schwarzeneggers are actually father and son. “How am I just finding out that Golden Boy from Gen V is Arnold Schwarzenegger’s son,” a viewer said.

As Patrick pointed out in his response, it’s doubtful that two people with such a moniker are unrelated. Schwarzenegger is “really not a common last name,” he quipped.

The actress and model is one of Arnold’s five children. The former California governor has two daughters, Katherine, 34, and Christina, 31, as well as a son, Christopher, 26, with ex-wife Maria Shriver, and a son, Joseph Baena, 26, with Mildred Patricia Baena.

Patrick, who in addition to Gev V has appeared in episodes of The Staircase and The Terminal List, will next star in season 3 of The White Lotus.

“I can’t wait to visit you on set,” wrote Shriver, 68, on Instagram when her son’s casting on one of her “favorite shows of all time” was announced in January.

“I fell in love with going to set with my dad,” Patrick told Teen Vogue magazine in 2015. “The best thing about acting is portraying a character that has a different life than yours.”

Arnold, meanwhile, also continues to garner screen credits. Following the 2023 docuseries about his life as a bodybuilder, actor and politician, he has starred in the series FUBAR and in State Farm commercials. A movie reuniting him with Twins and Junior costar Danny DeVito is also reportedly in the works.
