Joined by close friend and celebrity photographer Randall Slavin, the two premiered Slavin's Reach: 24 Portraits exhibition to benefit Theron's charity which is dedicated to reducing HIV/AIDS and sexual violence among African youth. Being a South African native, she does everything she can to raise awareness for the growing epidemic back home.
"I was born and raised in South Africa," the 36-year-old actress said. "It just always broke my heart knowing that with all the knowledge we have today about how not to be HIV positive, my country is the hardest hit by this epidemic."
Theron's charity has also provided mobile clinics to help improve care, HIV awareness and prevention amongst African youth. Click the video to see and hear more from last night's festivities.
