...why is Cheryl Cole famous?
  

I see her as a slightly dim, quite good looking woman that happened to be in the right place at the right time.  She has no obvious skills, yet is looked up to by millions of women and girls.
  
She cant sing (it's auto-tune overdrive on her songs), her accent is annoying, her presenting skills are weak and yet she earns a fortune on lowbrow television programmes and advertising.  She sits on the panel of television programmes that exploit individuals and she gives her views on their talent, yet she has none herself. Doesn't seem right to me.
  
The strange thing is, she doesn't have that "look" that some other celebs' have - the look that says "I know I'm a fraud and it's just a matter of time before you figure it out".  People like Kerry Katona have that look and it's one of fear.
  
Can anyone explain to me why Cheryl Cole is famous?
