Evangeline Lilly, known for her leading role in 'Lost', is pregnant with her second baby.

The thirty-five year old actress showed off her baby bump at the premiere of 'Ant-Man' on Monday, where she revealed to E! News that she is seven months along, and is expecting the baby in September.

The former Lost star, who already has a four year old son named Kahekili with her partner, Norman Kali, is having an easy pregnancy so far, she says.

"This is my second time around, and I find I've been pretty lucky," she said. "It's pretty straightforward, and I just love it. I feel good, I feel blissful."

Lilly obviously enjoys being a mother, and she will likely continue to expand her family once her second child s born.

In a 2014 interview, the star said that she wanted six children originally, and that she loves being pregnant. She says that she wanted to adopt four.

"My partner and I have really been through the ringer in the adoption world, and it's hard, so we'll see what happens," said Lilly. "Life is magically beautiful, and it brings you what is perfect."

She also added that becoming a mother helped her to find a sense of self and understand life's priorities.

"All I have to do is see my son to do that mental check that says, 'Is this really important? Do you really need to be doing his? Do you really care?' said the actress. "It helps put everything in perspective when things get stressful or when there's a demand or pressure on me."
