I don't care for celebrities themselves. For the most part, many are pitifully uninspiring as human beings, and should not be viewed as role models. Let's keep it real here, they are just Entertainers for Hire.

Being in the business I'm in, I do notice fashion and colors. Being a MuT member, I will notice m/u apps and techniques. Being a self-hair care guru, I do notice hairstyles.
