Miley Cyrus isn't the only one trying to show the world she's all grown up.

Justin Bieber released a video for his latest single, 'All That Matters' and all that matters to him is taking his shirt off and seducing the ladies.

I know he's trying to have a more grown up image, but some of the more provocative gestures he makes are somewhat laughable.

However, I was a young (er) girl once so I understand that Beliebers everywhere are probably hyperventilating right now.
