This irritates me. I mean, alot of things can irritate me, but she just looks stupid. What the hell is she doing this for if its not for attention to try and get people interested in her again?
The first thought that came to my mind was "she's doing this for shock value". She probably figures if she does something not expected of her to do, and its on tv, in the papers, and in the news, it might just bring her back and salvage whatever she had left or maybe give her a new angle to work with.
In some bizarre way, this is like when Michael Jackson dangled his baby off that railing in Germany. Even if its bad news, its good news for these people. It's publicity.
