In 1976, Robert De Niro married actor Diahnne Abbott. That same year, Abbott gave birth to their first child, Raphael De Niro. Robert also adopted Drena De Niro, Abbot's daughter born in 1971 from a previous relationship. The couple divorced in 1988, and De Niro began a relationship with actor Toukie Smith. The pair welcomed twins Julian and Aaron De Niro in 1995. However, by 1997, De Niro had married his second wife, Grace Hightower. The couple were together for 20 years before their 2018 divorce. Within that time, De Niro and Hightower had a son, Elliot De Niro, in 1998, and a daughter, Helen Grace, through surrogacy in 2011.

De Niro's new baby makes him the father of seven children. While most of his kids have opted to stay out of the limelight, Drena Julian are also actors. Drena has starred in "Joy" and "A Star is Born," while Julian made his debut in the 2016 film "In Dubious Battle."

Robert opened up about parenting seven children to Entertainment Tonight Canada, saying, "I mean, there's no way around it with kids. I don't like to have to lay down the law and stuff like that. But, [sometimes] you just have no choice. And any parent, I think, would say the same thing. You always want to do the right thing by the children and give them the benefit of the doubt but sometimes you can't."
