Joined by partner Sean Penn, Charlize wore a gold metallic minidress with gold fringing around the hem.
The star, 38, who has been a spokeswoman for the fashion house's J'Adore perfume for several years, kept her make-up and hair simple, and paired with nude heels meant all eyes were on the stunning dress which showed off her gorgeous legs.

New couple Charlize and Sean had been friends for 18 years before deciding to embark on a relationship. It was not until New Year’s Eve that the couple made their relationship public as they were pictured enjoying a holiday in Hawaii.
"It just kind of naturally happened, and before I knew it, I was in something that was making my life better - the people who really love me can see the effect it has had on me", Charlize told Vogue of the relationship.
"I know so well what I want to fit in my life," she said. "And the simple answer to that is: Unless he can make my life better? My life is really pretty good. What I guess I am trying to say is a friend kind of stepped into that role, and I really didn't see it coming... We were just really good friends."
