There’s been a lot of chatter about Justin Bieber’s bulge in his Calvin Klein campaign, with speculation that he “stuffed” his underwear in an attempt to appear bigger down there.

There’s been rumors that he used padding, that the ads are photoshopped or other claims that he artificially enhanced his privates. His trainer, Patrick Nilsson, is now setting the rumors straight.

"I can definitely confirm that he is a well-endowed guy," Wilson told Access Hollywood, admitting, "I sound weird saying that, but yes.”

A site called BreatheHeavy is claiming to have exclusive photos of the photos before they were allegedly retouched to make it seem like his crotch, biceps and chest were bigger.

Meanwhile, the original Calvin Klein model, Mark Wahlberg, might approve of the campaign but his wife Rhea Wahlberg accused them of “retouching” the photos.

Bieber has expressed his excitement to partner with the brand, nonetheless, tweeting he’s “Honored to be a part of the legacy.”
