Then: Before she won an Oscar for her transformation into a serial killer in 2004's "Monster," model-turned-actress Charlize Theron showed off her dark side in this photo posted to her official Facebook page. "Do you recognize Charlize with her bold brunette brows? #tbt," Theron's caption read. Nope!
Now: The 38-year-old Theron was back to blond on Monday as she hit the the 2014 Met Gala red carpet wearing a Dior gown and holding hands with her fellow A-lister, Sean Penn, 53. The affectionate pair, first photographed together in January, make quite a cute couple, no?
