I'm in total agreement with LaLaLaur - up till week 6, I had really disliked her because I felt she was cold, nothing behind the eyes etc. But since the sing-off she has really won me over and I think she's my new favourite (after Sarah). I thought her performance was the best by far tonight, and while I understood the panel's comments about her not connecting, I couldn't see any of the other Nancys doing it significantly better either (and the bias towards Sam is making my blood boil, but that's another story altogether). It's a huge feat singing that Whitney song and not sounding Karaoke, and I never like anyone singing that song on talent shows but for the first time I felt that she did it justice.
I really hope she's not in the bottom 2 because I think she's easily the most rounded and all-round competent performer left.
