What does it take to be a "star" on TV?

I was listening to a new story this morning – a guy who was a contestant on “The Bachelor” was arrested in Iowa for leaving the scene of an auto accident.

The news story described him as “a star”. As I see it, he was a contestant who was playing a game, but he wasn’t special. He didn’t show any great talent or skill – he just sort of showed up.

What make a star? Skills? Acumen? Knowledge? Or just being there and showing up?
