I hope she does well! Though I also hope she goes back to training soon, I really want to see her compete this season.
I used to do ballroom dance; the whole fake tan thing is really popular. I never did it myself, but the vast majority of female dancers did. Some of their partners did as well. I'm not a fan of it, but hey, it will wear off eventually :]
Also, I heard an interview with her saying that she has to be more "covered up" than the other contestants due to her age. I don't exactly see how that dress is covered up, but it's not my job to pick the outfits....
Are those extensions? It looks just like her natural hair and she has had quite a few months since competition for it to grow longer. I'm not sure, but she looks nice with long hair :]
