Justin Bieber is back in the studio, working hard. The Biebs was spotted in a recording studio overnight with up-and-coming rapper Future!

Justin posted the photo above on Instagram early this morning (Aug. 16), showing the pair perched on a mixing board with the caption, "In the studio making a smash with my bro @future." (Bonus: That's a real good look at Biebs' just-finished tattoo sleeve!)

No word if the project is for Justin's next release or Future's own album, scheduled to drop in November.

Both artists have been making collaborations news recently, with Justin reportedly guesting on Mike Posner's next album and Future helping out Miley Cyrus on her upcoming 'Bangerz.'

Speaking of collaborations, Biebs posted a great picture earlier this week of him and mentor Will Smith, posing like the BFF's they are:

The cute caption included by Biebs? "Me and uncle Will." Awwww!
