LOS ANGELES, April 14 (UPI) -- Mila Kunis wore a loose-fitting black dress to the MTV Movie Awards on Sunday night, where she picked up the "Best Villain" trophy for her role as the Wicked Witch of the West in Oz the Great and Powerful.

Kunis beat out Michael Fassbender (12 Years a Slave), Barkhad Abdi (Captain Phillips), Benedict Cumberbatch (Star Trek Into Darkness), and Donald Sutherland (Catching Fire) for the top prize.
