The star used her appearance on the red carpet last night to reveal the wonderful news and sent fans and followers into a tailspin in the process.
Posing for photographers and paparazzi, the former Lost star showcased her gorgeous bump in a stylish monochrome gown which left no doubt that the mum-of-one has been keeping schtum for quite a while!
And just incase there was any doubt, the 35-year-old star took to social media following her appearance at the Marvel premiere to confirm the big news.
Captioning the shot from the starstudded event, the talented brunette couldn't hide her joy, writing: "#proudmamma'."
Evangeline, who also starred in The Hurt Locker alongside Ralph Fiennes, welcomed her first child, Kahekilli, into the life she shares with fellow actor, Normal Kali, in 2011.
Congratulations to the lovely family!
