I'm not a huge fan but I will say that she comes off as someone who knows her mental limits and is not afraid to play on them to poke fun at herself. And a good sense of humor is something that I find appealing in anyone. Plus she's not afraid to do those 'I had zits' infomercials... lol.
On the other hand, at least she's not an idiotic, sadistic, stuck up slut-bag like Paris Hilton!
