Justin Bieber made headlines recently after his Calvin Klein photos were criticised for being photoshopped. Even the size of the pop star's manhood was questioned since it was reportedly enhanced to make it look bigger. However, the singer has finally addressed the criticisms through social media.

Justin took to his Instagram account on Jan. 15 to prove to everyone that he does have a muscular body, contrary to what some may believe. The photo posted by Mirror UK shows the 20-year-old inside the bathroom wearing nothing but a white towel wrapped across his hips. His collection of body tattoos are clearly visible so is his toned and defined abs.

According to Mirror UK, the selfie is clearly Justin Bieber's way of silencing the rumours that his Calvin Klein pictures were photoshopped. The singer himself even dissed the criticisms and captioned the image with a simple "Photoshop lol." His picture has since received about 1.2 million likes with one fan named melicruz08 calling him "perfect."

The size of the singer's privates was even questioned following the release of his Calvin Klein photos. Speculations claimed Photoshop was used to make the bulge appear bigger. However, Justin's trainer has since vouched for the singer and confirmed his photos were not edited.

"I can definitely confirm that he is a well-endowed guy," Patrick Nillson told Access Hollywood. Nillson claimed that he may sound weird attesting to the size of the singer's privates, but reconfirmed that "yes" the bulge was not enhanced.

The pop star also revealed doing a lot of hard work to attain his toned and ripped abs for his Calvin Klein photos. In an interview with US Weekly, the singer claimed he had to work out with Nillson for "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," he said. Even Justin himself documents his exercise routine through his Instagram account. According to Mail Online, a video has even circulated showing him doing some pull-ups at the gym even with a broken leg.
