Who needs Glastonbury when you’ve got your squad?

A catwalk full of Taylor Swift‘s most famous buddies joined her onstage for her 1989 world tour stop in London Saturday night.

While performing “Style,” Swift, 25, first brought on Gigi Hadid and Kendall Jenner and then tennis great Serena Williams (from “Wimbledon,” Swift said referring to the upcoming championships). She also brought out model friends Martha Hunt and Karlie Kloss.

Then, as the cheers among the 65,000-strong crowd grew slouder, on came actress and model Cara Delevingne.

“London, England make some noise for my friend,” said Swift. “One of your own, Cara Delevingne.”

Delevingne, clearly feeling the British spirit, joined the crowd of women while waving a huge Union Jack flag.

While Swift’s squad is no stranger to joining her onstage during “Style” (it’s become somethingof a trend during her 1989 tour) this is the largest group she has gathered together for a single show.

Earlier, the friends were seen catching up and chilling backstage, joining up with Kate Hudson and Emma Watson, who both posed for photos with Swift while she met with fans.

To add to the fun, as support acts John Newman and Ellie Goulding played, Swift’s mom Andrea, who was recently diagnosed with cancer, cheerily greeted guests at the show, which was part of the British Summer Time festival.
