Justin Bieber‘s chugging an enormous pint of irony — after raging out at paparazzi, he is now paying them to create content material for brand spanking new album, “SWAG” … TMZ has discovered.

It is a fairly gorgeous plot twist … the singer-songwriter made a cope with a photograph company to make use of the audio from a video shot final month, the place he lashed out on the paparazzi for capturing him as he left a restaurant.

We’re informed Bieber’s camp made the photograph company signal an NDA … so, their representatives aren’t allowed to debate phrases of the deal, equivalent to how a lot JB paid.

The clip of that indignant alternate seems in his new tune, “STANDING ON BUSINESS” … a reference to the viral video the place the Biebs — a blue hoodie and sweats — sporting screamed that phrase on the paps on the road.

Within the video, he tells them he is a father, and he deserves a little bit extra respect … earlier than telling somebody mouthing off to him that he is standing 10 toes down on this scenario.

‘STANDING’ begins with the audio from that alternate, earlier than influencer Druski jumps in and corrects Bieber’s pronunciation — to make him extra fearsome to his photog foes.

Backside line … Bieber in the end made a cope with his enemy. Ya may say he spent the cash to reclaim his voice — however the photograph company’s taking his test to the financial institution, in order that they’re winners too.
