Her exceptional talent, her radiance and her strong commitments, perfectly echo Lancome's values," Lancome President Youcef Nabi said in a statement to Access. "We are convinced she will embody the brand in the most sublime way possible."
Kate Winslet, Anne Hathaway and Uma Thurman have all fronted the brand.
