It's a boy for Evangeline Lilly!

Former LOST star Evangeline Lilly (31) and her boyfriend Norman Kali (the production assistant on the set of the hit show) have welcomed their first child -- a BOY!

That's all the deets we have for now, since the Canadian actress is remaining MUM -- which is actually no surprise because she never announced or confirmed her pregnancy. Remember we got the news when all of a sudden she was spotted far along into her pregnancy?

Well, she was spotted again -- back to her wee self already and looking GORJ carrying her newborn! Check the photo over at PEOPLE!

Congrats to the family!

Love! xo Haley-O
