Justin Bieber's Calvin Klein photos were reportedly retouched to make his penis look bigger.
The 20-year-old singer—who has been unveiled as the face of the brand's latest underwear adverts alongside model Lara Stone—is also said to have had his biceps, back muscles and thighs enhanced by photo-editing experts.
What's more, a source connected to the shoot has claimed he behaved inappropriately on set, telling breatheheavy.com: "He was basically a douche. He hit on Lara several times and she had to stop him, basically calling him out on being just a child... Bieber specified he wanted to look taller and buff. Bigger bulge implied."
The claim comes shortly after Justin said his impressive-looking physique was all down to hard work.
The "Boyfriend" hitmaker said: "I work out with my trainer, Patrick Nilsson, five days a week for about 45 minutes each.
"We do three days splits: back and triceps one day, chest and biceps on day two, shoulder and legs on day three, and abs every other day.
"I'm not on a special diet, but I do try to watch what I eat. I do eat unhealthy sometimes—I am a 20-year-old guy!"
