Olivia Wilde, Kerry Washington are poshly pregnant

Could this be Oscar's most stylishly pregnant red carpet ever?

Olivia Wilde and Kerry Washington were a couple of bump Barbies in black-and-white Valentino and mauve Jason Wu.

"It was my favorite," Wilde told Paste BN's Andrea Mandell on the red carpet about her mod look, which clearly channeled one of Valentino's crowning Oscar glories, Julia Roberts' winning look from 2001. "So classy!"
