Iconic star of the 2000s, Christina Aguilera marked several generations of fans and the very history of pop culture. This year, a surprise guest in Cannes to give an exceptional concert during the evening of amfAR (which participates in research against AIDS), the American star gives himself up to the cameras of Vogue. We followed her behind the scenes of her performance, from her hotel room in Cap-Eden-Roc to the backstage of her concert. Just a few moments before going on stage, she tells us about her beauty rituals, her fantasies of French love and her constant search for authenticity. Because it is indeed Christina Aguilera who, from the beginning of the 2000s, drew the contours of the Y2K aesthetic, in full comeback this season: chaps pants, chrome nail art, rhinestone jewelry, dramatic eyeshadow, low-rise pants… For Vogue, Christina Aguilera analyzes the very essence of this iconic style.
