To be fair, she's no different to most celebs on Twitter - most of them retweet their fan's comments.
Twitter is one big ego trip for all celebs who have an account.
Oh, I know every celeb does it. That's why celebs are a funny lot. I just find it funny (and sad) that a celeb would seek out what people think about something personal and intimate to them - like she's putting her backside out there for people to review like it's a single/album or something
That's modern day celebrity I guess
