Squad goal: Kendall, Cara, Karlie, and tennis star Serena Williams join Taylor Swift at London concert

Model Kendall Jenner, Cara Delevingne, Karlie Kloss, Gigi Hadid, Martha Hunt and Tennis star Serena Williams joined friend Taylor Swift onstage during the pop superstar's "1989" tour.

The 25-year-old singer recruited many famous friends to appear in her Bad Blood music video, but several of her friends instead strutted the stage during a live performance of Style in London on June 27.

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 UK flag.

Style, which peaked at number 6 on the Hot 100, was released as the third single from Swift's album 1989.

Swift's tour itinerary will bring her next to Ireland and Canada, and she will then return to the US for a pair of concerts on July 10-11 in East Rutherford, NJ.
