Riley & Eva Play Peek-a-Boob at Cannes!

Despite the film being about a friendship-gone-wrong between two men played by Mark Ruffalo and Steve Carell, all eyes were on Eva Longoria and Riley Keough at Foxcatcher's Cannes Film Festival premiere.

And they aren't even in the movie!

While the actors looked dapper in generic tuxedos, Longoria went full-on bombshell in a full-length nude dress with a high neckline and a keyhole opening that plunged diagonally from her chest to her midriff, exposing a lot of her left breast in the process.
