Blake Lively, Kerry Washington, Olivia Wilde and Emily Blunt all had one thing in common at tonight's Met Gala -- these four ladies had the best accessory you can possibly bring to a red carpet.

A baby bump!

Each of the women already has one little one at home, but excitedly showed off their growing bellies on the red carpet tonight. Olivia Wilde and Emily Blunt walked together, both wearing custom Michael Kors gowns, while Kerry Washington affectionately held her stomach under an incredible Marc Jacobs dress.

Blake Lively was one of the last people to arrive for the Gala this year, wearing a gorgeous pink, flowing Burberry gown. She walked with Christopher Bailey, creative director of the brand.
