But one post stood out to us in particular, and we bet you can guess who's...
"To the man who has showed me more beautiful places in this past year than I have ever seen in my whole life. Happy birthday, Cole. Thank you for all of the adventures and here's to many more 🌙 ," Lili Reinhart wrote.
M E L T I N G.
We know that Lili and Cole are ~officially dating~ right now, so it basically makes her b'day post 3,000% more adorable.
After the two were spotted kissing at Comic Con, it seems their relationship has been excelling, like how they went on a movie date with both Lili's mum and sister last week.
Ahh, our #Bughead hearts.
