Not only did Taylor Swift recruit half of Hollywood for her "Bad Blood" music video, but she can get them to join her onstage whenever she wants!

Last night T. Swizzle performed in London as a part of the British Summer Time festival at Hyde Park, and she brought Gigi Hadid, Kendall Jenner, Serena Williams, Karlie Kloss, Martha Hunt and Cara Delevingne to the stage when she sang "Style." When Cara appeared, Taylor told the crowd, "London, England make some noise for my friend ... One of your own, Cara Delevingne!" Love it!

Earlier in the day, the girls posted a bunch of selfies backstage, and they were also joined by A-list ladies Kate Hudson and Emma Watson! Not to bring up that feud with Katy Perry again, but we're pretty sure Taylor has way more celebs on her team!
