Everyone Gets Teased

And everyone can be picked apart.
 Even celebrities have it tough.
Alicia is a great performer, nice to look at, and a philanthropist - but she is said to have bad skin.

 Rihanna is often mentioned as having a big forehead and acne scars.

 Megan Fox - acne scars.

 Cameron Diaz - acne.

 Sex and the City's Sarah Jessica Parker is often called horse-faced and cross-eyed.

And this girl is probably teased for having a ghetto booty.
No matter what, many people like to make themselves feel good by making others feel bad.
It's just easier than doing the work for themselves.
TMZ, Entertainment Tonight, Access Hollywood, People, The National Enquirer, ... have all created successful business models around the idea of teasing people who have/do what others with they could have/do.
