You're probably already aware that Selena Gomez dropped her single "Lose You to Love Me" in October, earning her first-ever No. 1 on the Billboard Hot 100.
You also probably already know that Selena's ex-boyfriend, Justin Bieber, got married to model Hailey Baldwin just a couple of weeks before that.
It's safe to say fans got their detective hats out when Selena's song dropped, analysing the lyrics and coming to the conclusion that it definitely seems to reference her past relationship with Justin.

And Selena seemed to confirm that the song was about Justin in an interview with Ryan Seacrest, revealing that it was written over a year ago — around the time she broke up with Justin — but she didn't want to release it at the time.

But it all kicked off when Hailey Bieber posted this screenshot on her Instagram story the very day Selena dropped her song.
