They believe that Bieber was referencing his notorious on-again, off-again relationship with Gomez in his new song, "Ghost."
The song, which included lyrics like "I miss your touch some nights when I'm hollow" and "If I can't be close to you, I'll settle for the ghost of you, " had fans curious.
Some fans went on Twitter to share their thoughts about the song and found like-minds. While some fans assumed the song was about Gomez, some pointed out that it was simply about losing someone. Well, he lost Selena!
