Ant-Man star Evangeline Lilly used Monday night’s premiere of the film to make a big announcement.
The actress revealed she’s pregnant with her second child by stepping out on the Los Angeles red carpet in a gown that essentially confirmed the news for her.
Lilly, 35, and partner Norman Kali (a production assistant, PEOPLE notes, that she met on the set of Lost) are already parents to a 4-year-old son named Kahekili.
Ant-Man opens in theaters July 17. For more on Lilly and her pregnancy, head over to PEOPLE.
