The Riverdale stars flew to Hawaii to celebrate New Year's but we're betting that we weren't supposed to know this as there was no mention of it on either star's social media.
Lili took a snap of a gorg landscape and captioned it: "Everywhere in Hawaii is a real life Windows desktop," but did not reveal that she was with her co-star.
However, lucky for us thirsty fans, a bunch of Riverdale stans snapped pics with the pair and OH MY GOD they look adorable!
There was no New Year's Eve kiss pic, but we can only imagine how it would've gone down!
So let's see. They've been spotted kissing. They've travelled together. And now they've rung in 2018 side-by-side.
If this isn't proof that Bughead exists IRL, we don't know what it is!
