Patrick Schwarzenegger and Joseph, the illegitimate son of Arnold Schwarzenegger, photographed together playing sports

Patrick Schwarzenegger and his half-brother Joseph Baena were photographed together bonding in Los Angeles, ten years after it was revealed that actor Arnold Schwarzenegger had a child with the family's housekeeper.

This is the first time that Patrick, 27, and Joseph, 23, are seen together, while enjoying a sports session on Monday, with Joseph's girlfriend, Nicky Dodaj.

This appearance comes as a surprise to everyone... after years of a complicated history between Joseph and his half-siblings, including Patrick, 27, Christopher, 23, Christina, 29, and Katherine Schwarzenegger, 31, who now seems to be on the mend

Arnold's former official wife, Maria Shriver, is the mother of their four children, while he secretly had Joseph with his then housekeeper Mildred Patricia Baena in 1997

In June 2019, Joseph had not attended the wedding of his half-sister Katherine when she married actor Chris Pratt

Still, Joseph had posted Congratulations! on Katherine's wedding Instagram photo from her big day - which was held in Montecito, California - with two hearts and a champagne bottle emoji.

It was a wedding with many celebrity guests, including Katherine's parents, Maria and Arnold, as well as Guardians of the Galaxy director James Gunn and actor

Joseph follows Patrick and Katherine's official Instagram accounts, but they don't seem to follow him back.
