In 2011, it became public knowledge that Schwarzenegger had fathered a child outside his marriage to Maria Shriver<\/a>. The actor and his then housekeeper and assistant, Mildred Patricia \u201cPatty\u201d Baena, welcomed Joseph in October 1997 \u2014 five days after Schwarzenegger\u2019s youngest son with Shriver, Christopher, was born. However, they didn\u2019t know the Kindergarten Cop<\/a><\/em> star was his father for years.<\/p>\n In addition to Christopher, Schwarzenegger shares three other children with Shriver, his now ex-wife: Katherine Schwarzenegger<\/a>, 36, Christina Schwarzenegger, 34, and Patrick Schwarzenegger<\/a>, 32. Schwarzenegger and Shriver divorced in 2011, shortly after the news of Baena broke.<\/p>\n Baena attended the premiere of Fubar<\/a><\/em> Season 2 with his father in June 2025. During a red-carpet interview with Entertainment Tonight<\/a><\/em>, he opened up about hitting the gym with Schwarzenegger.<\/p>\n \u201cWe train together. We love working out together,\u201d he said. \u201cHe\u2019s a great workout partner.\u201d<\/p>\n When asked if he\u2019s ever been approached about playing a younger version of his dad, Baena admitted, \u201cI\u2019ve heard it a few times. It would be a great honor.\u201d<\/p>\n Read the latest entertainment news on TV Insider<\/a>.<\/p>\n<\/div>\n<\/div>
