The puzzle that is Justin Bieber's fourth studio album seems to be slowly coming together, and it looks like we just got another big piece.

It appears that the Biebs has enlisted super-producer Rick Rubin, or as Justin calls him "the man," to lend his expertise to his next album.

Justin's manager, Scooter Braun, reposted the pic of JB and Rick with the caption "working on some history," and we're assuming he doesn't mean homework.

This would be the first time that the "Confident" singer and Rick have gotten in the studio together, and I have to admit I'm pretty excited to see what direction Justin goes in with Rubin's guidance.

The seven-time Grammy Award winner has a beyond impressive background, working with everyone from Adele and Kanye West to Eminem, Ed Sheeran and even Lady Gaga. (Believe me, the list goes on and on and on.)

Justin recently confirmed to Karl Lagerfeld for V magazine that he was going to "start working on a new album and a tour" for the new year and that he was "excited to get back to work."

In 2014, Justin may have been giving us clues on his Instagram as to who else he's working with on this album. The Calvin Klein model has been caught in the studio with T.I., Austin Mahone, Cody Simpson, Chris Brown and Ariana Grande.

I think I speak for many Beliebers out there when I say: We want more details, Justin!
