What goes on backstage at the Victoria Secret runway show? I spent yesterday afternoon hanging with the models, makeup artists, and hairstylists, trying to figure out the difference between bronzer and self-tanner. (Haha, just kidding. Kind of.) Some quick numbers: 68: The number of hair extensions used by stylist Sam McKnight 15: The number of days Alessandra Ambrosio works out each year. ("And all before this!" she says.) 40: Total number of hours the styling team spent working yesterday. 8.5: Bottles of body bronzer used. Click through to see the show's major players at work, from Lily Aldridge to Tom Pecheux and back. And don't forget to watch everything come to life Tuesday, November 30th at 10pm EST on CBS.
