She doesn't need a FB or to open the show to be the best , just like in 2013. She opened Parisian Nights in that red outfit and looked absolutely perfect, and people forgot about everybody else.
In the VS show thread they saw her pic next to Secret Angel section, so she might open that segment (or the show if that is the opening section).
Last two years she didn't look her best at the VSFS. In London she looked tired and last year the makeup was horrible. I hope that changes this year! I mean she looked AMAZING at the fashion week just a month ago (Marc J, Versace, Bottega V), she looked 10 years younger, I really have no idea how VS menages to make her look average...
