The 'Black Swan' actress has been signed up by the French fashion house to front its spring fashion campaign, which has been shot by Mikael Jansson.
Delphine Arnault, deputy general manager at Dior, said: "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. We are looking forward to a long relationship with her."
Mila, 28, says she is still in the process of learning about fashion but has always been a huge fan of Dior's designs.
She told WWD: "I'm honestly just learning about fashion. In my daily life, I don't wear the most feminine pieces. But I love to feel feminine when I'm on the red carpet. I find that Dior is an incredibly grounded house. I always thought what Dior does is so sophisticated, feminine and beautiful."
She also said she enjoyed shooting the campaign, revealing: "They made me feel incredibly comfortable. I can't say it was the hardest thing to do."
