Julian is following in his dad Robert De Niro's footsteps by getting into acting. Robert, for his part, is pretty private about his six kids and rarely talks about them. In 2019, he told Us Weekly, "I love my children, just being with them. It's not easy. Sometimes it's fun and you love your kids, and sometimes you want to kill them! Then, when you have the good moments, you forget about the ones that weren't good."
