Justin Bieber's Penis Size Confirmed in Photos

Scroll for the photos. The ad showed Justin posing for #mycalvins, a campaign since promoted by the likes of model Kendall Jenner and teen pop icon Billie Eilish. Justin was shot in black-and-white and while only in white briefs with the Calvin Klein logo across the stretchy waistband - quite the bulge was also on show.

Justin, who has been cleaning up his image and recently saw 25-year-old wife Hailey clap back over allegations that his marriage to her is unstable, was reported to be, well, not the most pleasant on-set.

"Honestly, it was never something that I was going to do for a living," he said of his music career. Continuing, he added: "At 13 you’re not even thinking about that, you know? I was just playing for fun and uploading videos on YouTube because I wanted to show my family. That’s when Scooter [Braun] found me."

The new Balenciaga face, who now comes complete with his popular Drew House clothing line, further said: "So when Scooter was contacting us, I started to think, like, “Wow, this could actually be my life. I could actually do this for a living and make music and travel the world.” So that’s when I started getting excited. And when I moved down to Atlanta, I met Usher …"

Justin continues to make headlines for regular sightings with Hailey, with whom he attended this year's Met Gala.
