The heavily-tattooed 20-year-old singer has posed in a new advert alongside model Lara Stone, wife of comedian David Walliams (scroll down for photos).
Bieber follows male celebrities including actors Mark Wahlberg and Jamie Dornan and footballer Freddie Ljungberg who have all featured in iconic Calvin Klein campaigns.
On Twitter, Bieber said he was “honoured to be part of the legacy”.
In the video above he explains that “I’ve been wearing Calvin Klein underwear for years in the hope of one day becoming the Calvin Klein model, but never really thinking it would come to reality. Now that it’s here it’s a dream come true.
The men’s underwear market is increasingly lucrative and competitive, and is worth £700 million in the UK alone.
Last year model David Gandy (Marks and Spencer) and former footballer David Beckham (H&M) launched their own underwear ranges.
The black-and-white six second promotion was shared on Calvin Klein’s Twitter account on Tuesday, and was appropriately captioned, ‘Drum roll… #mycalvins’.
First, the promo saw Justin seated at a drum set, where he showed off his rapid drumming.
After a moment or two at the set, the Believe star finished off the steamy commercial by pulling in Lara for what appeared to be a kiss.

MailOnline was the first to exclusively report in July that Justin had shot an ad for the designer brand.
A Calvin Klein source said: ‘Justin has shot for Calvin Klein, we hope the results will be released later this year.’
It was never confirmed whether or not Justin – whose signature style is low-hanging jeans with exposed briefs – had inked a deal with the company.
