Chloe Grace Moretz had the reaction that ALL OF US had seeing Shawn Mendes in those sexy new photos for Vogue Italia!
The actress tweeted out to the singer using a gif of herself looking, well.... very flirty!
And of course Shawn tweeted right back at her and she hit him back again!
Well of course we LOVE THIS! Maybe it was sleep depravation, maybe it sparks flying?! Time will tell!
