Natalie Portman and Mila Kunis stepped out for the LA premiere of Black Swan last night during LA's AFI Film Fest presented by Audi. The actresses play arch-rivals in the film, which is one of Buzz's picks for Fall, but they gushed at the screening about working with each other. Natalie was the belle of the ball in a floral dress by Rodarte, the design house that also created her ballet costumes, as she smiled for pictures with Mila, in a leather skirt from The Row, and their costar Winona Ryder. Also in attendance was choreographer and Club Monaco model Benjamin Millepied, who is Natalie's boyfriend, though the two once again avoided posing together. Benjamin saw both Natalie and Mila through the harsh dance training required for their roles, and Mila told us the process was so demanding that the first thing she did when shooting wrapped was eat — a lot! Check out our red carpet interviews below and on today's PopSugar Rush.
