Why attractive people act so insecure when they don’t get attention?

I’ve been working at a modeling agency for about 2 years, we get models doing their profiles everyday. The majority of the models are beautiful and handsome but they carry themselves with an air of arrogance and confidence (now not all of them are this way, just the majority). What’s weird thought is that they act and react differently when an average girl like me doesn’t give them attention or acknowledge their beauty like the majority of my coworkers. So why, why attractive people act so arrogant and yet insecure when not given the attention or appraisal they expect especially guys?
