Jeremy Bieber showed his pride in his son's genetic achievements, after naked photos of Justin were published online.
This isn't the first time Justin Bieber has been caught without his pants on.
This also isn't the first time his father creepily gushed about the size of his son's penis in front of the world.
Justin was recently photographed on holiday in Hawaii, enjoying a nude dip with his rumoured new girlfriend, Aussie model Sahara Ray.
The revelation prompted Justin's dad, Jeremy, to Tweet the phrase "my boy" alongside a cactus emoji.
While the Tweet has since been deleted, Jeremy Bieber also shared a photo of himself next to the CN Tower in Toronto and tagged his son. The image isn't captioned, but many fans believe it is a reference to the nude photos.
This isn't the first time Jeremy has celebrated his son's manhood. After nude pictures of Justin were leaked in 2015, Jeremy took to Twitter, quipping: "What do you feed that thing. #proud daddy."
The censored images of Justin were published by New York Daily News but it didn't take long for the uncensored images to surface.
The photos arrived mere days after Justin's rival, Orlando Bloom, was also snapped in the nuddy while on holiday with his girlfriend, Katy Perry.
Justin, 22, also seems to be in the grips of a new romance - this time with an Australian!
Sahara Ray, 23, is a model and designer from Torquay, Victoria and has previously been linked to Aussie pop star, Cody Simpson.
