“Mad Max: Fury Road” was an important film in Charlize Theron’s career as it marked an important time in her life. On Thursday, she shared a sweet, rare pic of herself on set with her first child, Jackson, lying on her chest. “I became a mom right before we started shooting,” she captioned the touching photo, which features Jackson with a purple heart emoji covering her face. “At least my child will forever have the fun fact of ‘I spent most of the first year of my life in a war rig’ (special appearance by my incredible costumer Inge Hough).” Theron has previously opened up about raising Jackson as a girl after she came to her at the age of three saying she was not a boy.
