'Ant-Man' premiere surprise: Evangeline Lilly is pregnant!

We knew Evangeline Lilly would look stunning on the red carpet for the world premiere of Ant-Man, but we had no idea she'd be showing off her pregnancy glow.

The actress, who plays martial arts expert Hope Van Dyne onscreen, debuted her belly at Monday night's red carpet in Hollywood. On Instagram, Lilly used the hashtag "#proudmama" to hint that baby No. 2 is on the way.

A few hours earlier, she posted a photo of herself rubbing her belly backstage on Conan.

Lilly gave birth to son Kahekill in May 2011.
