Justin Bieber has got his kit off again, this time, posing topless for the April Reinvention issue of Men’s Health magazine.

And, it seems JB is VERY proud of his toned torso, allowing photographer Lensman Peter Hapak to take10 photos of his shirtless self - all of which were untouched.

[related]Boasting of thisfact during a behind-the-scenes video of the shoot, JB is states: “It's not Photoshopped! For all you fools out there saying it's Photoshopped!

“I love the fact that I got in shape the past two years and I'm finally getting recognition for it.”

According to The Daily Mail, the 21-year old went on to claim: “You know I'm just getting bigger, man. It's like, my shoulders don't fit in some things.”

As well as his body, the Confident singer - who split from Selena Gomez in October - went on to reveal that he prefers being in a relationship to being single.

Justin explained: “I’m very much a relationship guy. I like to bounce ideas off the person that I love. I like having a real connection.”

And, when it comes to his bad boy behaviour, Bieber insisted: “[It's] almost like I grew up for the public but I didn't necessarily grow up.

“There were things I had to do, as far as the way I had to make relationships, and conversation, but as far as actually growing up, there were a lot of things I missed out on.”

He continued: “I'm growing. I'm learning. I'm a human being. This has really been a big year for me, as far as figuring stuff out. This is almost like a full 180 from how I was. Yesterday — a year from yesterday — I was in jail.”

Justin went on to admit that despite his worldwide fame, he sometimes wishes he could disappear, explaining: “I wish I had the Batman thing where people didn't know I was Bruce Wayne, like I had a costume or something.”
