Evangeline Lilly is expecting again! The former Lost actress stole the show at Marvel’s Ant-Man premiere by premiering her other new project, her second child.

As US Magazine reports, Lilly, 35, appeared on her first red carpet since December in a tight one-shoulder gown that revealed her growing baby bump. In the new film, Lilly stars opposite Michael Douglas and Paul Rudd playing the character of Hope van Dyne.

Lilly was previously married to Murray Horne and romantically linked with her Lost costar Dominic Monaghan, but eventually found love with a Lost production assistant, Norman Kali. The couple has a 4-year-old son, Kahekili.

Although the news is a bit of a surprise, Lilly had hinted at wanting to expand her family in a January interview with Ocean Drive magazine. “What I wanted originally was six kids,” she said. “I frickin’ love being pregnant.”

“I’m one of those lucky women who just had a blissful pregnancy, but I wanted to adopt four,” she added. “My partner and I have really been through the ringer in the adoption world, and it’s hard, so we’ll see what happens. Life is magically beautiful, and it brings you what is perfect.”

No due date or gender was announced. Ant-Man hits theatres on July 17.
