This is an evergreen surprising question in almost the minds of everyone as to how some people get partners who are so attractive that one can never think of getting one! Not only it happens in the case of celebrities but it happens in the lives of ordinary people too.
It’s because beauty is not find in the face but it lies in one's heart. Anyone will look for a partner he/she is comfortable with, share emotions, interest etc. One might get drawn towards physical attractiveness, but their relationship won't last longer if there is no connection between their hearts.
It's a human tendency to find better than what they are.They'll always crave for a person who is much better than them.A good looking model will look for a same level match rather than a medium looking guy.
But these relationships don't get the actual meaning of what we call Love.There is no use of looks or amazing physical appearance if there is no understanding between the two. They'll end up with their ego problems.
Anyone can love your looks, but it's your heart and personality that make people stay!
