Bosses at the French label asked the Les Miserables star if she wanted to front a series of adverts for their fragrance Very Irresistible, and Seyfried admits she didn't hesitate, responding, "F**k yeah!"
Speaking to Women's Wear Daily, executive Nicholas Munafo insists the blonde beauty is the perfect spokesmodel for the brand, explaining, "Amanda is a chic, sexy woman who is a perfect fit for Givenchy."
And Seyfried, who donned a gorgeous purple Givenchy gown to the 2012 Tony Awards, is excited about the project, adding, "I'm proud to be a part of (the brand) because what they do is really cool - they're so artistic. And I feel like I have a foot in the fashion industry now."
The 27 year old's ads will debut in October (13).
