The cat's out of the bag for the "Lost" actress and her longtime boyfriend Norman Kali, as the recent premiere for her latest film, Marvel's "Ant-Man," has showed that the usually very fit Evangeline Lilly's pregnant with the couple's second child after their 4 year-old son!

It's not only that Evangeline Lilly's pregnant, but she's visibly expecting, which says that she's been keeping her coming baby a secret for the past few months - but, in any case, the Canadian actress who played an elf in the recent "Hobbit" trilogy is looking adorable with her big expectant baby!

According to Entertainment Weekly, the revelation that Evangeline Lilly's pregnant came as she walked down the red carpet arm in arm with her production assistant boyfriend, in a lovely gown that showed her big belly during the premiere of the Paul Rudd-led superhero film, as she looked incredibly happy to share the news with the world.

The Daily Mail reports that Evangeline Lilly's pregnant figure made its debut at the Hollywood Dolby Theater (where the Oscars are held) last Monday, as she shined in a black and white one-shoulder Halston Heritage dress during the Los Angeles premiere, looking under her shoulder in gorgeous black and silver heels.

 "The last time I was off work, I had no children, I had a partner who was busy working 18 hours a day, so I had all day to meditate and love on my baby and just be pregnant," the actress explained to People Magazine, as she announced that Evangeline Lilly's pregnant. "This time, I have a 4 year old I'm running around after, I'm working full time and I have a stay-at-home daddy so he's always around ... I just haven't had the same kind of time to give this my attention."

Still, the "Hurt Locker" actress has spoken in the past about wanting to expand her family, saying she and her partner wanted to adopt as well.

In any case, congratulations to the actress and her boyfriend now that Evangeline Lilly's pregnant!
