The Victoria's Secret Fashion Show is one of those shows that really likes to one up itself. And each time it sets the bar pretty high. Last year, Jay Z, Kanye West, Nicki Minaj and Maroon 5 performed alongside VS Angels like Miranda Kerr, Karlie Kloss and Erin Heatherton. So where do you go from there? Hire Rihanna and Justin Bieber, obviously. And Bruno Mars for good measure. The show ran through different themed vignettes (including months of the year, the circus, pinball), but it was most refreshing to see new girls like Cara Delevingne and Jourdan Dunn make their debut. And of course, veterans like Miranda Kerr, Adriana Lima and Alessandra Ambrosio attracted serious applause and screams from the crowd.
