Kerry Washington and Blake Lively also dressed up their growing bellies.

Something must be in the water. Following pregnancy announcements from Emily Blunt, Blake Lively and Olivia Wilde, news broke on Monday morning that Kerry Washington also is expecting. And all four ladies were on the scene for Monday night's Met Gala at the Metropolitan Museum of Art in New York City.

Mamas-to-be Wilde and Blunt stepped out for fashion's biggest night as each other's date (maybe their other halves, Jason Sudeikis and John Krasinski, were busy?). Wilde glowed in a custom black stone-embroidered halter column Michael Kors gown and Jennifer Fisher earrings, while Blunt shone in a custom sequin-embellished lace gown, also designed by Kors and Forevermark Diamonds.

Washington wasn't afraid to dress up her bump after word spread that she was expecting baby No. 2, as she held onto her belly during the red carpet.

Lively, who is reportedly pregnant with her second child with Ryan Reynolds, was accompanied by Burberry creative director Christopher Bailey, who designed her blush pink pleated silk organza and chiffon gown with a corset top and A-line skirt. A petal-detailed cape rounded out the elegant look.
