Justin Bieber may be currently promoting his latest album Purpose, but he does not need to resort to posting nudes to ramp up publicity. The 21-year-old singer has denied reports circulating online that he displayed his manhood in two racy pictures posted on Snapchat.

The black-and-white images, which shows someone that resembles Bieber laying down with no underwear quickly sent fans into meltdown after going viral online. Although both photos were headless, the collection of tattoos appeared to match that of the Sorry hitmaker.

However, sources close to Selena Gomez's ex tell TMZ it's a bad Photoshop job and it's definitely not him. Rather than get stressed about someone trying to cash in on his fame, the heartthrob is said to be laughing off the incident as nothing more than a bad joke.

His lawyers fired off a cease-and-desist letter to the tabloid, threatening to sue, according to the Hollywood Reporter. "We recently became informed that your company has obtained and is distributing unauthorized photographs of our client including images showing him without clothing."
