I certainly don't want to take anything away from Jennifer Lopez because she's done so much with her life. She's influenced and inspired so many people. However, I wouldn't go as far to say that she's the most beautiful person in the world. In fact, how can anybody be #1?
The reason I say that is because beauty is so subjective. What one person thinks is "the most beautiful" could be entirely different from another person's idea of beautiful.
Young girls and women read People magazine and think, "I have to look just like Jennifer Lopez to be beautiful!" I stopped reading many celebrity/fashion/beauty magazines because they have brainwashed so many women into thinking that you have to look like a certain celebrity to be considered beautiful. I know that when I was in my 20's I used to read these magazines and feel insecure about my own beauty or aspire to be famous just so I could be noticed.
So many women waste all this time wishing they could be beautiful, focusing on their physical flaws, and spending so much money to be beautiful on the outside that they never stop to reflect on their own self development. Choose to be grateful and happy for what you have and you will bring out your own beauty from within. Be loving towards yourself and other people and you will be beautiful on the outside too.
