Surprise! ‘Lost’ star shows off baby bump on the red carpet

Photographers got more than they bargained for when Evangeline Lilly took to the red carpet last night in Los Angeles for the premiere of Ant-Man.

Although she had made no official announcement, it was clear from the actress' blossoming bump that she was pregnant. Evangeline, who hasn't been pictured on the red carpet since the premiere of The Hobbit: The Battle of the Five Armies back in December 2014, happily posed for the cameras in  stunning black and white Halston Heritage dress.

This will be the Hobbit star's second child with her husband Norman Kali – the pair already have a four-year-old son together named Kahekili. Prior to meeting Norma, Evangeline was married to Murray Hone, and she also dated her Lost co-star Dominic Monaghan.

The expectant mum confirmed the news herself via Instagram yesterday, first posting a picture of herself backstage at Conan O'Brien cradling her bump in a gorgeous yellow dress, and later sharing an image from the Ant-Man premiere with the hashtag #proudmama.

Evangeline had made no secret of the fact that she was hoping to get pregnant again, telling Ocean Drive magazine back in January that she had big plans. "What I wanted originally was six kids. I frickin’ love being pregnant," she said.

"I’m one of the lucky women who just had a blissful pregnancy, but I wanted to adopt four."

Looks like little Kahekili will have quite a few younger brothers and sisters in that case!
