Justin Bieber is gearing up to bare it all with his Believe: Acoustic album.

No, we don’t mean he’s planning to moon us all again. (Not that we’d complain about that either, though.)

The Biebs is baring his personal life and, we’re guessing, his relationship with now-ex Selena Gomez (awkward) in his brand-new song "Yellow Raincoat." In the track, it’s easy to see -– or hear, at least -– that Justin has come a long way from his side-swept hair and purple hoodies. He’s actually turning into a grown man!

On "Yellow Raincoat," Justin almost sounds unrecognizable with his matured and grown-up voice. Bravo, Justin. Bravo.

But here’s the awkward part: we’re kinda guessing that Justin dedicating this song to his former flame, Selena.

“Cause the fame, and the money, and the girls will drive you crazy," he sings. "Guess I'll put on my raincoat, my yellow raincoat/ Baby it's keeping me fright/ I put on my raincoat, my yellow raincoat/ You know exactly why." If the rumors about what caused the breakup are true, maybe he picked up a cheaply-made raincoat.

You can hear the full-length Believe: Acoustic when it drops January 29th!

Do you think Selena will take Justin back after hearing this tune?
