WATCH: Taylor Swift Joined by Kendall Jenner, Cara Delevingne and More on Stage in London

Now that’s a girl band. 

Taylor Swift has been joined by a number of famous friends throughout her 1989 World Tour, but last night’s show (June 27, 2015) was her most star-studded yet.

Kendall Jenner, Cara Delevingne, Karlie Kloss, Gigi Hadid, Martha Hunt, and Serena Williams joined the “Bad Blood” singer onstage in London’s Hyde Park.

Wearing coordinating black and white outfits, the ladies walked down a stage runway as Swift introduced them to a sold out crowd. Delevingne even marched down the stage with the U.K. flag, as Swift performed her hit “Style”.

And just when you thought Swift’s #SquadGoals couldn’t get any stronger, the girls were joined backstage by Emma Watson after the show.
