Gorgeous girl!

Blake Lively rocked a red hot Monique Lhuillier gown for the New York City premiere of The Age of Adaline, and we can't stop staring at her perfect physique. How is it that she gave birth just four months ago?!

The 27-year-old actress posted a photo of her getup on Instagram later and wrote, "Workin Emoji Chic. It's the new thing. Watch out Norm Core," along with fourteen of the infamous salsa dancer emojis. Our fav!

Lively stars as Adaline, a woman who is "rendered ageless after an accident." In a recent interview she revealed that after her hit CW series Gossip Girl wrapped, she wasn't feeling any scripts -- until she got her hands on this one.

"I feel like magic doesn't exist much in films these days, unless it's a superhero movie or has a wand," she told Very Aware. "But that magic in humanity, magic in a quiet film, is rare ... When [movies] like this come along, they're called 'little movies that could.' Adaline is sort of between that, because it's a movie that can reach a broader audience, but it still has that magic and humanity."

We can't wait to see it!
