Kendall Jenner, Cara Delevingne, Karlie Kloss, Gigi Hadid, Martha Hunt and Serena Williams joined Swift onstage in Hyde Park, a stop on the pop superstar’s 1989 World Tour. In video footage from the show, the ladies can be seen having fun making their way down the catwalk as Swift sings -- and Delevingne even marches down the stage with the U.K. flag.

“Style,” which peaked at No. 6 on the Hot 100, was released as the third single from Swift’s album 1989. Swift’s tour itinerary will bring her to Ireland and Canada next, and she will then return to the U.S. for a pair of concerts on July 10-11 in East Rutherford, N.J.
