Say hello to Biotherm's new face, Amber Valletta. The Revenge star has been brought on by the brand to front its forthcoming Blue Therapy anti-ageing line, according to WWD. In a statement the brand said of the signing: "Actress, model and campaigner, at 38, Valletta is the epitome of a strong woman with the self-confidence to achieve her ambitions and campaign for what she believes in." Valletta joins current face Sasha Pivovarova, as well as Tyson Ballou and Geoff Huegill who represent Biotherm Homme. Expect to see Valletta's ads in September.
