Singer Justin Bieber has poked fun at photoshopped images of his toned abs by flaunting his real body.

The 20-year-old took to Instagram Wednesday to show off his body in a shirtless picture wearing only a white towel, reports aceshowbiz.com.

`Photoshop lol,` Bieber captioned the images.

After Bieber's Calvin Klein photographs were released online, BreatheHeavy.com posted some photoshopped images showing the `Baby` hitmaker with fewer muscles and a smaller bulge in his underwear.

Bieber then threatened to take legal actions against the website if the fake pictures were not taken down and apology issued.

Shortly afterwards, the website issued an apology and a retraction of its article about Bieber's photographs.

`Bieber denies the photo is real, and I respect that and will believe him,` the site wrote, adding `No harm, no foul. We sincerely apologize to Bieber for the hit to his ego and to the millions of tweens on social media we upset: Swag swag swag, on you. Chillin' by the fire while we eatin' fondue (sic).`
