He may have had numerous hits across the globe as well as the unwavering support of 20 million Beliebers on Twitter, but on UK shores Justin Bieber is still largely known to anyone over the age of 14 as "the 'Baby' singer". Its success (along with a movie and kiddie Christmas album) has easily kept him afloat until now, but three years on and at the tip of his 18th year he finally appears ready to enter phase two of his career.
The phase in question is the not-a-boy-not-yet-a-man one. "If I was your boyfriend I would never let you go," he whisper-raps on the intro, before unleashing his more familiar falsetto on quite frankly a killer of a chorus. "I'll keep you on my arm girl, you'll never be alone," he assures over a jam of toe-tapping acoustics, leaving us with an overwhelming urge to teach him another of life's important lessons: the art of playing hard to get.
