Nude photos of the 21-year-old went viral after the singer was snapped on holiday in Bora Bora with rumoured girlfriend Jayde Pierce.
The What Do You Mean singer was walking outside his beachside villa in the buff when the photos were taken, with noticeable tan lines around where his swimming trunks should have been.
Jayde was also in the pictures, although she was wearing a fluffy white robe.
It is believed that the photos were taken without Justin’s knowledge, and that he was on a private resort at the time.
Following the publication of the images on various websites, the Biebs’ fans were sent into a frenzy, with “What Do You Peen” becoming a trend.
Bieber has yet to release a statement on the set of photos, although he has shared other holiday pics to his Instagram account.
He posted a snap of a new tattoo hovering over his belly-button reading “Purpose” – the name of his new album, due out next month.
