Oh, how we love a makeover! And this brunette-to-blonde transformation on Black Swan star, Natalie Portman, does not disappoint. Portman debuted her golden tresses this weekend while attending a dinner in support of husband, Benjamin Millepied, and his involvement in L.A. Dance Project. The new 'do is for an upcoming film role but the Oscar-winning actress is being tight lipped about the details. We do however have intel on how Portman achieved the drastic hair-color change from the woman who did the dyeing herself, Tracey Cunningham for Starworks Artists:

"Natalie makes a beautiful Blonde! She needed to make the change for an upcoming movie role, and using Redken's Blonde Dimensions we achieved a gorgeous, multi-dimensional Golden Blonde."

Cunningham is the true Hair-Colorist to the Stars and names actresses like Gwyneth Paltrow, Jennifer Lopez and Charlize Theron as some of her dye-hard clients. So, it's no wonder Portman would call her up to make this jaw dropping metamorphosis. Cunningham met with Portman at Salon Benjamin in West Hollywood where she has set up shop until construction ends on Mèche, her new salon with Neil Weisberg. We're obviously Team Blonde and hope Portman keeps up the golden locks even after her top-secret movie wraps. Well done.
