James Diamond/James Maslow

James Diamond is portrayed as the "Prettiest Boy Of The Group". He is obsessed with his face and hair; he always keeps head shots of himself and his lucky comb in his jacket or his pants. In Big Time Interview, Carlos said, "His comb is his best friend" when Madison Michele asked James who was the best looking in the band. He is portrayed by James Maslow. 

Personality

James is shallow, driven, sometimes an airhead, and, like Logan, sometimes panics under pressure, but is a good friend and looks out for his band mates. Of his band mates, he is closest to Carlos, whom he loves to play video games and goof around with. He is described as solid-voiced and driven beyond belief.
