Justin Bieber and Hailey Baldwin have been friends for years.
But the singer and the model appeared to take their relationship far out of the friend zone in early 2015 when Bieber shared a photo of the two kissing.
(UPDATE: And now the stars are engaged?!?!?!?!)
This game of tonsil hockey came after numerous denials, mostly by Baldwin, that she and Bieber were up to anything tawdry.
“We're just friends. I've known him for a very long time, since I was about 13,” she told E! News in early 2015, adding that people simply "assume" things because they are the opposite sex.
Still... should we have seen this romantic entanglement coming? Probably.
Just consider Bieber and Baldwin's history of intimate Instagram photos...
As you can see here, that's what Bieber claimed about Baldwin back in the winter of 2014. And, hey, it may have been true at the time!
On Their Way Out
Bieber and Baldwin do run in the same crowd, but they have always made time to snap many photos together as well.
We Should Have Known...
... if Hailey was willing to put up with that hat, she clearly had feelings for Bieber that go back awhile.
In Turks and Caicos
Baldwin and Bieber celebrated the end of 2014 in Turks and Caicos. The former didn't even seem to mind the latter's dumb hair color here.
Happy New Year!
Hailey and Justin spent New Years together in 2014 as well, snapping this selfie in the process. But their tongues remained in their mouths.
Hailey was one of many friends on hand to help Bieber celebrate his 21st birthday. But she was one of the only ones to wrap her arms around him for a picture.
What a Jokester
Bieber is joking around and acting all sad while chilling here with Baldwin in April of 2015.
Looking Very Cozy
Baldwin is once again resting her hand on Bieber's shoulder in this selfie from June 2015.
Still Looking Very Cozy
Another selfie from this same poolside hangout in Beverly Hills.
We thought Bieber as a Heat fan. Either way, he's clearly a fan of spending time with Baldwin.
It Is SO On!
Justin Bieber and Hailey Baldwin continue to insist that they are just friends. We believe them. But look at this photo!
