Justin Bieber Men's Health - The Grammy-winning pop star Justin Bieber is gracing the cover of the "Men's Health's" April 2015 issue. The Justin Bieber Men's Health cover shows the 21-year-old shirtless, muscular and definitely all grown up. However, some reports claim that the cover has been Photoshopped.

According to E! Online, some reports are saying that the magazine has artificially bulked up the singer's muscles for him to look a little more ripped than he actually might be.

Of course, the new Justin Bieber Men's Health cover will be defended by the pop star, who put down accusations in his behind-the-scenes video from his photoshoot.

"Being on the cover of Men's Health is really really cool. I love the fact that I got in shape the past two years, and I'm finally getting recognition for it," said Bieber.

"It's not photoshopped for all you fools out there saying it's photoshopped," he added.

The Justin Bieber Men's Health cover Photoshop accusations was also brushed off by a "Men's Health" spokesperson

He reportedly told E! News the Biebs looks "amazing" on the April cover.

The magazine also addressed the Justin Bieber Men's Health cover Photoshop speculations, tweeting out a picture of the April issue's cover, with the caption, "Our April issue has @justinbieber-can he reinvent himself? See 10 (unphotoshopped) photos."

This isn't the first time Bieber faced Photoshop flack. His "thing" reportedly appeared to be surprisingly large when he appeared in Calvin Klein's underwear ads, launching an immediate "photoshopped!" blacklash.

However, the website BreathHeavy.com, which initially published their "findings," later retracted their bulge-alteration accusations and posted a note saying the original pic "was Justin Bieber's Calvin Klein photo sans Photoshop."

The site also said it had received a cease and desist letter.

The Justin Bieber Men's Health cover Photoshop accusations might easily be escaped by the 21-year-old. But he can't easily get out of his past mistakes, such as getting arrested on the suspicion of drunk driving in Miami. Bieber reportedly holds himself accountable for such mistakes, however placing blame on growing up in front of the spotlight.

"This has really been a big year for me, as far as figuring stuff out," he said in the "Men's Health" issue. "This is almost like a full 180 from how I was. Yesterday-a year from yesterday-I was in jail."

The Justin Bieber Men's Health is the latest attempt on an image rehabilitation tour for music's bad boy, according to TIME. The tour reportedly include a public apology for his behavior and an upcoming Comedy Central Roast March 30, which ads he also appears shirtless in.

The cover line of the Justin Bieber Men's Health "Reinvention Issue" also claimed that Bieber "explains himself" in the issue.

However, the accompanying quotes from the interview, released with the Justin Bieber Men's Health cover are unclear, according to Vanity Fair.

 "There's a part of me that I don't ever want to grow up. I want to always remain . . . to have that sense of purity inside of me where I don't . . . I don't want to lose that sense of purity," said the pop star.

He added, "I'm very much a relationship guy," reflects that he had to "grow up so quick," and regrets that, "as far as growing up there were a lot of things I missed out on."
