The 42-year-old actress also opens up about how she 'struggled mentally' through the adoption process.
Charlize Theron may be a single mom, but she doesn't consider herself her kids' only parent.
"I knew that I would have to have my mom help me if I was going to do this as a single parent," Theron shares. "To not acknowledge her coparenting my children would be a lie.”
"I struggled mentally through the adoption process. Some of my lowest points in my life were dealing with the first time I filed; it really took an emotional toll," she confesses. "There were so many situations that didn’t work out, and you’d get attached and have all your hopes up and then just get crushed.”
Now, Theron says she's concerned with making sure her African-American children "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," she expresses, before noting that she won't travel with her children to certain parts of the U.S. because "racism is much more alive and well than people thought."
"We can’t deny it anymore. We have to be vocal," she says.
Theron got real while talking about parenting with ET in February. See what she said in the video below.
