Mila Kunis joins Black Swan

She'll play Natalie Portman's rival

Now that Darren Aronofsky's ballet rivalry pic Black Swan is finally kicking into high gear, Mila Kunis has been added to the cast.

Kunis will play Lily, a ballet rival for star Natalie Portman, who torments her and may simply be a figment of her imagination.

As the pair prepare for a big performance, stranger and stranger things start happening.

Kunis certainly has the spindly build for a ballet dancer and with funding finally in place, Aronofsky can start shooting later in the year.
