Talk about a spur-of-the-moment hair change! Backstage at last night's Victoria's Secret Fashion Show, Karlie Kloss unveiled a new chin-skimming bob shortly before hitting the runway. Although it's a drastic difference from VS's trademark flowing manes, we thought the shorter crop looked great on Kloss! Enter lead hairstylist Orlando Pita, who was well-equipped with extensions to temporarily undo the spontaneous cut. "Honestly, it may be unbelievable, but we have probably spent about $75,000 just on extensions alone," he told during the taping. "There is a lot of hair in this room, and a lot of money! There are fans on the runway, so all of the girls get extensions added to avoid getting gaps in their hair while walking." And after spending time in Pita's chair, Kloss strutted down the catwalk with long, bouncy waves. Crisis averted!
