Justin Bieber is known for his fame, fortune, hot girlfriend and zillions of endorsement deals -- so it's easy to forget that the guy can actually sing. In this shot, labeled "Writing hits," Bieber reminds us why he's a star: his music!

Hard at work on 'Believe,' Biebs is pictured looking serious in tone-appropriate black and white, grainy photo. We wonder which lyrics he was jotting down here. Maybe 'BoyFriend?'

While he's taken some flak for not writing his earlier material, keep in mind that the guy just turned 18. Was he supposed to sing about razor scooters and asking for raises in his allowance before?
