During a recent interview with Us Weekly , the singer revealed how he got involved with the whole CK campaign in the first place, and how he got those amazing abs, too.
"I've wanted to be involved with Calvin Klein for a while now," Bieber explained to the mag. "Earlier this year, I put up a picture on Instagram of me in their boxer briefs with the #mycalvins tag, and people went crazy for it and it got their attention."
Justin's whole project with them was top secret, and the shoot took two days to complete. "It was actually two-and-a half because I got sick during the second day," Justin spilled. "Behind the scenes, everything ran like clockwork, we'd come in, do glam, and get right to shooting."
And as for that sick bod? "I work out with my trainer, Patrick Nilsson, five days a week for about 45 minutes each," he reveals of his fitness routine. "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."
Surprisingly, the Biebs doesn't have to diet and can pretty much each what he wants and still have that physique. "I'm not on a special diet, but I do try to watch what I eat," he said. "I do eat unhealthy sometimes, I am a 20-year-old guy!"
