But luckily for us, they eventually gave up on the mystery and let fans in on their secret: THEY'RE IN LOVE.
Stepping out together at the Met Gala was all the confirmation we needed, despite the fact that we had seen them kissing multiple times beforehand.
But one thing they still hadn't done was go Instagram official... and everyone knows that's an integral part of dating in 2018.
Now, Lili has posted a BTS snap of her and Cole at the Met Gala, and they look so cute.
It's about damn time guys.
