Charlize has been candid about her role as a mom to two Black daughters. During an interview with Elle, in 2018 she said: "I want them to know who they are, and I want them to be so [expletive] proud of who they are.

Charlize adores being a mom to her two girls 

"Building confidence for them right now is an oath I made to myself when I brought them home. They need to know where they come from and be proud of that.

"But they're going to have to know that it's a different climate for them than it is for me, and how unfair that is. If I can do something about that, of course I'm going to."
