Justin Bieber, 'I f*ck b*tches!' [WATCH]: Selena Gomez's ex-boyfriend roasted by comedian Chris D'Elia, declares himself a true 'ladies man' [VIDEO]

Justin Bieber likes to bang chicks.

The "Believe" crooner said so himself!

Comedian Chris D'Elia invited the Biebs onstage for a surprise appearance during his set at Hollywood's Laugh Factory on Friday (Dec. 13). And Selena Gomez's ex-boyfriend said something sort of controversial... (but not at all surprising).

D'Elia totally ragged on Bieber's "swag," making fun of his horrible fashion choices and even proclaiming that in the end, the "As Long As You Love Me" crooner's "only f*cking himself."

To which the Biebs proudly responds, "...and b*tches!"

Well, okay then.

Maybe the Biebs was trying to make a "cool" joke, but things just sort of turned awkward.

Now, the clip's since gone viral online.
