While he’s an acting veteran, fatherhood is quite a new concept to Joaquin. Indeed, he and fellow actor Rooney Mara became the parents of a son named River in 2019, a child named after Joaquin’s brother, who died in 1993. Joaquin is quiet about his personal life and has shared virtually no details about his son. Paparazzi have spotted Joaquin, Rooney, and River out and about in California, but not much is known about their home life.
