Justin Bieber and Chris Brown walk into a bar…

We wish we were joking, but the beleaguered duo did indeed party together on Tuesday – and Bieber posted a shot on Instagram to prove it.

Brown and the Biebs, both currently on probation, are seen mugging for the camera along with a rather large (and all male) entourage. Although she's not pictured, TMZ reports that Brown's girlfriend Karreuche Tran was also in attendance. It all went down at Los Angeles hotspot Bootsy Bellows on the Sunset Strip.

"Back at it," Bieber captioned his photo, although it remains unclear exactly what "it" is, although the photo comes one month after the duo was spotted in the recording studio together.

Also according to TMZ, the night ended without an ounce of drama from either troubled star. Keep it up, kids!
