Actresses Gabrielle Union and Sanaa Lathan, along with R&B singer Ciara — 3 of the sexiest women in Hollywood, FYI — showed their pretty faces Wednesday night (Oct 12) in California as they supported actress/philanthropist Charlize Theron at her Africa Outreach Project photo exhibition.

Proceeds from the charity event will go straight to Theron’s Africa Outreach program, which is committed to reducing violence and HIV/AIDS among African youth.

Also spotted at the benefit, held at the Annenberg Space for Photography in Century City, CA were “Dexter” star Michael C. Hall and comedian/actress Sarah Silverman.
