The Victoria’s Secret Fashion Show is just days away, and we’re finding out more about which models are on the roster. One new revelation: Rosie Huntington-Whiteley won’t be hitting the runway when the show films November 9th. “I’m not walking this year,” she told InStyle.com exclusively at a Beverly Hills bash for Burberry Body. “I’m working that day.” However, the model-turned-actress has some tips for the girls who will grace the stage. “It’s all about confidence and state of mind,” said the 24-year-old Transformers star, who made her debut for VS in 2006. “Do whatever it takes to get to that place. I feel most comfortable when I’m filled with love.” As for managing the wings? “I used to really not like getting the big wings,” she explained. “It’s really tough, so hold on tight!”
