Dior executive Delphine Arnault insists the actress was an easy choice: "Mila Kunis is a very talented young actress; she embodies the true modern woman. Her performance in Black Swan was remarkable. She is very gifted."

And while Kunis admits she's always been a "jeans and T-shirt" type girl, she's excited about the partnership.

She tells WWD.com, "I’m honestly just learning about fashion. I find that Dior is an incredibly grounded house. I always thought what Dior does is so sophisticated, feminine and beautiful."

The actress joins Charlize Theron, who currently fronts the fashion label's J'Adore perfume campaign.
