Star Spotting: The First Rule Of Justin Bieber Fight Club Is That There Is No Justin Bieber Fight Club (PHOTO)

Justin Bieber werques his best “baller boxer” lewk! 

Look, landing a No. 1 song on the charts is a massive feat that deserves to be celebrated. (Hell, getting a No. 1 ANYTHING deserves to be celebrated.) So when Justin Bieber posted this nearly shirtless photo of himself along with the caption, “When they tell me #Rollercoaster is #1,” we were kind of like, OK, fine!

If the Biebs wants to celebrate the success of “Roller Coaster” by dressing as either a bling’d-out Hugh Hefner or a super-ripped, robe-wearing boxer about to take his “pump-up walk” to the ring, then we totally understand.

And sure, we know that some of you are probably like, but WHY is he wearing a robe to celebrate when he could be showing off his glistening abs — or more generally, WHY A ROBE PERIOD?! Sadly, we don’t have the answers.

However, one could posit that JB’s peculiar apparel serves as a subtle nod to his boxing bestie, Floyd Mayweather, Jr.? Maybe he’s gonna re-enact every scene from “Fight Club”? Orrrr, perhaps this silk robe helps with, um, “easy access” when Justin’s getting ready to “re-enact” all the verses from “PYD” IRL? Don’t talk to us for the rest of the night. We’ve found the image we wanna go to bed with. Byeeee!
