Gucci has announced that Charlotte Casiraghi will be the face of its new cosmetics collection, which debuts in September. Casiraghi is Grace Kelly’s granddaughter, and fifth in line to the throne of Monaco.

The stylish daughter of Princess Caroline of Monaco has long been a muse for Gucci, recently starring in Gucci’s Forever Now campaign in Fall 2013, which was shot by Bruce Weber.

The new cosmetics collection will be manufactured by P&G Prestige.

Celeb makeup artist Pat McGrath is the creative design director responsible for the makeup looks at Gucci’s runway shows – perhaps she is influencing the development of the new products.
