I think she comes across as a very ordinary young lady who has been pitched into a culture where being beautiful and sexy and perfect is all.
She has tried over and over to squeeze herself into this 'ideal' and she simply is not equipped.
She isnt pretty. She isnt sexy. She is ordinary. I would think that this sort of lifestyle is incredibly stressful even if you were some stunning telly blonde, let alone a girl who is a bit of a frump.
I think that is why she has overcompensated with all this Hello/Ok type of talk. She is trying to prove to herself that her life is perfect and she is some sort of Victoria Beckham character.
I think its very sad and how awful for her to have been beaten up by her partner. Its so public. She cant hide away and how many other smug twats are rubbing their hands in glee because she has got her comeupense (sp)?
I bet there wouldnt be half the 'ha ha she had it coming' if she were Cheryl Cole or similar. She would be a tragic hero then. Cheryl Cole was almost cannonised because she had a husband who shagged around. 
Badly done OP, badly done.
