The Victoria's Secret Fashion Show doesn't air until Thursday night, but the masterminds behind the sexy shindig have given us a sneak peek at not only the Angels' getting-ready process but also at Lady Gaga's performance of "Million Reasons." Gaga, who joins The Weeknd and Bruno Mars as the annual show's musical talent, sings her emotional hit along with the lip-syncing help of Victoria's Secret models Alessandra Ambrosio, Jasmine Tookes, and more backstage. There are also quite a few shots of the models strutting their stuff in preparation for walking the runway, so watch it above!
