The star, who won the best actress award for her role in Monsters Ball back in 2004, debuted a brand new dark brown bob. Contrasting her duck egg blue gown, Theron opted for a bright orange lipstick and kept the rest of her make-up simple.
The South African beauty's hairstylist Adir Abergel wrote on Instagram: “Decided to chop it all off before the big moment. #cantwaittoshare #oscars2019 #hairbyadir.”
While her make-up artist Kate Lee shared this stunning backstage selfie.
