It depends entirely on how one defines "attention whore".
I can't stand the kind of people who go out and be obnoxious specifically so that everyone will pay attention to them, but that's mostly because they're obnoxious. I don't have any particular problem with people who want to be the center of attention. All the more power to them, I certainly don't. But if they're a dick about it, I will respond in kind.
In short, don't be a dick and you can attention whore all you want.
