What's wrong with Nicola Roberts?

I am watching this right now, a href="http://www.funnyordie.co.uk/videos/c3a1f0b250/rock-profile-cheryl-cole-and-nicola-roberts-pt-2" rel="nofollow"http://www.funnyordie.co.uk/videos/c3a1f…/a and even though it's funny, it got me thinking of all the crap Nicola gets thrown at her, what's so wrong with her, I think she's the prettiest one. I really like her style and think she's beautiful, why do other people have a problem with her?
