I always find this message board, and people's reactions to the housemates so interesting. Being American, I don't really know any of these "celebrities." However, I did see The Apprentice, so I know Luisa. I hated her on there.
However, I don't think she's done a thing wrong on this show. She's been very fair and even-handed, and doesn't seem at all to be doing things out of self-serving intentions. I don't find her desperate to win -- certainly not like Dappy, Lee, Jim, Linda, Lionel, all seem to be. I'm quite liking her.
