The 40-year-old "Mad Max: Fury Road" actress said the affection between her infant daughter, August, and her four-year-old son, Jackson is "sacred and beautiful," reported People magazine.
"It is a love that is unbelievable to watch. I'm watching something so sacred and beautiful. He (Jackson) walks into a room and he doesn't even look at her (August) and she just lights up.
"I'm in front of her going crazy trying to get a reaction... It's so beautiful," Theron said.
