The Victoria's Secret Fashion Show is all happening! The big event doesn't air until Dec. 5 on CBS, but the taping went down this week in Paris, with some major performers: Lady Gaga hit the runway for her first time, as did Bruno Mars and The Weeknd, who performed in 2015. We're getting ready by taking a look at all the backstage chaos, hot performances, and runway glamour from years past. From the over-the-top set designs to the barely-there lingerie, it's pretty amazing to see how far the show has come since the late '90s. See Gisele Bündchen, Heidi Klum, Naomi Campbell, Alessandra Ambrosio, Miranda Kerr, and even performers like Justin Timberlake, Taylor Swift, and Usher when you scroll through now.
