Why A person can be a Star?

I can understand why so many people follow the famous star. The person who can influence people must have a sure advantage. Some for the appealing appearance, some for the superior achievement. When a person is famous, her behavior, activities, dresses, and others will be adored by his/her fans, same to me. If I like a star, then I will try to follow her step. Although I can not afford the expensive make-up and other things, I still want to follow her and try my best to be her style.
