Jessica Chastain is the new face of Yves Saint Laurent.

The Help actress was "thrilled" to be named the ambassadress of the iconic French fashion house's latest perfume, Manifesto.

The flame-haired beauty - who shot to international fame in 2011 thanks to her role in Terrance Malik's The Tree Of Life alongside Brad Pitt - commented, "Yves Saint Laurent is a brand that inspires me deeply. Since its creation, the brand has conveyed strong values that I cherish, such as an unwavering commitment, absolute love and feminine audacity.This new fragrance is an emblem of it all. I am thrilled to be part of this beautiful adventure."

Manifesto will be introduced in France on August 27 and the rest of Europe in September. The perfume will be available in the US in 2013.

"We were won over by the very subtle strength of Jessica Chastain, her solar charm, her free mind. Jessica embodies the quintessence of Saint Laurent's femininity, a woman of her day and age, independent, determined, never where you expect her to be," Stephan Bezy, international general manager of Yves Saint Laurent Beauty, told WWD.
