Taylor Swift brought more of her famous friends on-stage to surprise fans. The latest sudden stage-appearance happened on Saturday while Swift was performing at London’s historic Hyde Park. When it was all said and done, Swift had a total of six A-list celebs on stage while she performed her hit Style.

Among the special guests were Kendall Jenner, BFFs Cara Delevingne, Gigi Hadid and Karlie Kloss, as well as Serena Williams and Martha Hunt. The celebs had a makeshift catwalk session during Swift’s song, all to the ecstatic screams and cheers of those in attendance.

Just after the show Swift shared a photo on social-media for fans that weren’t able to attend the sold out event.

At just 25 Swift has been on top of the world these past few months. The latest headlines involving the performer came when Swift’s open-letter to Apple concerning the company’s music-streaming service quickly caused Apple to change their policy. The sudden change happened almost immediately after Swift published the letter on Tumblr.

Within the letter Swift wrote, ” Apple Music will not be paying writers, producers or artists for those three months. I find it to be shocking, disappointing and completely unlike this historically progressive and generous company.”

All of that aside, Apple changed its tune and Swift announced that her new album ‘1989’ will be made available on Apple Music when the streaming service launches this year. Following that announcement Swift stated, “This is simply the first time it’s felt right in my gut to stream my album. Thank you, Apple, for your change of heart … In case you’re wondering if this is some exclusive deal like you’ve seen Apple do with other artists, it’s not.”
