First Kylie Jenner with her do-rag, and now this!

Hailey Baldwin is currently in the Big Apple enjoying fashion week, and the model decided to try out the latest head scarf trend when she hit the streets this afternoon. The blonde beauty wore a lace cami and a silk skirt to complete her look, and her abs looked absolutely insane!

So just how did she get her rock hard midriff? A cleanse!

"Right now, I’m on a metabolic detox. I’m trying to reset my body before I get into the craziness of all this traveling and running around. It’s like a cleanse that you have to do with like protein powder and all this different stuff and you have to eat a certain type of way. I eat healthy regardless but it’s very much more scaled down," she told People.

Heartbreak is always a great diet, too! The Guess stunner was none too pleased to learn about ex Justin Bieber's new romance with Sofia Richie, and that's the kind of news that makes any girl lose her appetite.

Lookin' good Hails!
