I find it incredibly ironic that a Christina Aguilera fan, of all people, is trying to make another popstar, who is widely known as being one of the nicest people in the industry, seem bitchy and stuck up.
I remember there being occasional rumors of her being bitchy back during the ITZ era (not to say she was ALWAYS like that, but I think that was the time that she had the most attitude, since she was feeling very rebellious and I suppose over the industry). I know this was a bit before the start of that era but eh it probably happened. But regardless of that period of time she's still probably one of the nicest celebs overall considering how horrible some of them can truly be behind doors and whatnot, so whatever.
