For the most part that is the point for people to obsess and want to be like these people and have these attractive people to advertise, do certain roles, etc. I have noticed that your looks also don't get you all the attention, just being famous can make a person look attractive according to some fans of certain people. Someone mentioned that Ed Sheeran wasn't super hot or anything but they found him attractive. Others do make a point that the right stylist, make up artist, etc can make the celebrity good looking. Some are but not all we all know that. Oh surgery is a big part too.
