Arnold Schwarzenegger has recently opened up about his extra-marital affair with housekeeper Mildred Patricia “Patty” Baena which bore him a son, Joseph Baena, and subsequently ended his marriage to Maria Shriver in 2011. Let’s get to know more about the “Terminator” actor’s youngest son.

Joseph, was born five days after the ex-California governor welcomed son Christopher with Shriver.

“It’s just my f–k-up,” the former bodybuilder bluntly said of his affair.

“Remember it’s not like we had a feud,” he explained to People magazine in an interview published Sunday. “We didn’t have a fight.”

Who is Joseph Baena?

Joseph Baena who just chalked 26, was born on Oct. 2, 1997, following an affair with Schwarzenegger’s housekeeper Mildred that began in 1996. The actor did not realize Joseph was his son until he got older and began to resemble him.

According to, while Mildred raised Joseph on her own, she occasionally brought him to the Schwarzenegger household, where she worked for two decades until she retired in 2010. Mildred also has a son and a daughter from her previous marriage.

When did Joseph get to know Arnold Schwarzenegger was his father?

According to, Joseph was in middle school when the news broke that Schwarzenegger was his father. He told Men’s Health he remembered the day “very vividly.”

“I was in the eighth grade. Fifth or sixth period. And I get called out of class to leave,” he shared. “My mom’s there, and she’s like, ‘We gotta go — everyone is finding out about you and who your father is.’ ”

Joseph was 13 when the life-changing news became public. “Your body’s transforming; your mind is transforming. And now my life transformed before my eyes,” he said.

Is Joseph Baena following in his father’s footsteps career wise?

Schwarzenegger’s youngest son is following his father’s footsteps into the film industry. He got his big break in Bully High (2022), which follows a Pakistani high school exchange student as she deals with bullies at her American high school. Joseph played Eddie, the class president.

In 2021, he teased a film project called Lava with a shirtless photo on Instagram. The movie was filmed on location in Hawaii.

Deadline reported in April 2023 that Joseph had joined the cast of the upcoming action film Gunner. He’ll play a deputy sheriff named Wally alongside names like Morgan Freeman and Luke Hemsworth.

Naturally, Joseph has turned to his Jingle All the Way actor dad for advice in his acting career, but he said those requests were “very minimal” because he wants to “figure it out” on his own.

“The main thing is just the work, putting in the work, putting in the reps,” he told PEOPLE. “That’s the No. 1 thing that we always discuss. And for me, it’s just been me figuring it out myself. … There’s no shortcuts in acting, and in really anything.”

Joseph also shares his dad’s passion for fitness, and they often hit the gym together.

“This selfie was taken moments before my dad suggested I do ‘forced reps’ for the rest of the workout,” he shared on Instagram beside a photo of the pair at the gym. “You have to go all out and absolutely NO cheating when you train with him, so you know I’m going to be hurting tomorrow.” Joseph added his dad helped him “get every last rep.”

He’s also learned a thing or two about bodybuilding from his dad, having posted several look-alike shots in his dad’s iconic poses.

What is the son of the former Mr. Olympia currently up to?

According to, Joseph is currently a licensed real estate agent. He announced the career move in 2021, sharing a photo on Instagram with a caption saying he’s “not your average realtor.”


“Super excited to start a new career in residential real estate,” he wrote. “Looking forward to growing and learning from my amazing team @aria_properties, but more so looking forward to putting you guys in a new home!”

He made his first big sale in 2022 and announced the news on Instagram. “SOLD!!!” he wrote. “Congratulations to my clients for trusting myself and @aria_properties to sell their beautiful Santa Monica Property!”
