"My job as a parent is to celebrate them and to love them and to make sure that they have everything they need in order to be what they want to be," she explained. "And I will do everything in my power for my kids to have that right and to be protected within that."
Theron adopted Jackson in 2012 and her second daughter, August, in 2015.
Last April, Theron spoke to Elle US about her decision to adopt.
"Adoption is a very personal thing, I know people whom I love dearly who don’t feel that they could raise another child as their own. I respect that. But for me and I can't be the only person out there, I never saw a difference in raising an adopted child versus my own biological child."
She added, "This was always my first choice, even when I was in a relationship. I was very honest with my partners that I was open to having my own biological kids but that adoption had to be a part of my life."
