But NOW, it looks like they're finally opening up to their fans, and sharing their love on social media.
While Cole has posted many photos of Lili on his Instagram before, none have been very lovey-dovey. Until now!
Yesterday, Cole posted this near-kiss photo of him and Lili, captioning it, "It's pretty, pretty late."
CALM our beating Sprousehart!
And it seems like they were having a pretty romantic night together, because Lili also posted on Twitter, writing, "Fashion week is great and all, but have you ever spent a rainy weekend inside cuddles up with your bae?"
Cannot actually deal.
