Still think of Bieber as a scrawny teenage pop singer?

“It’s good to really take a step back and be appreciative and understand that life brought me to an incredible place.”—Justin Bieber, April 2015 Men's Health cover guy

"I had to grow up so quick," he shares. "And it was 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."

Still, despite his admitted immaturity, he says he never wants to lose his "sense of purity."

"There’s a part of me that I don't ever want to grow up," he says. "I want to always have that sense of purity inside of me where I don't...I don't want to lose that sense of purity."

As for his famous romances, Bieber insists he's "very much a relationship guy" and prefers brunettes in jean shorts and tank top or spandex. But his love for relationships goes deeper than that.

"I like to bounce ideas off the person that I love," he explains. "I like having a real connection."

And watch out for his next tattoo. The already heavily tatted-up Bieber reveals what new ink he wants next, and its personal meaning to him.

"I want 'LL' tatted right here," he says, pointing to his chest. "When you're Low, Lift. Because we often want to keep our heads down. But we should lift our heads."

between this and champagne flabby no thx. our male pop stars need to beef up.
