What makes people celebrity?
Is it their beauty?
I heard that it is beauty that really makes those celebrities stars

I have two questions
I will give a scenerio. Though not real, but just assume

There are two ladies, Joy and Grace. Joy is very attractive and has a good voice.
Grace is average looking, but her voice is better than Joy's voice ×3.

1. According to your own opinion, which one do you think will be celebrated more

2. Which one would you love more? Be sincere
