Taylor Swift has done it again!

Yes, we loved when she brought Mariska Hargitay out onstage at a recent Philadelphia concert. And don't get us started on the countless meet-and-greets she's had with deserving fans before and after shows.

But on Saturday night in London, the "Shake It Off" crooner got every Swiftie super jealous when we learned her London show didn't feature one special guest. Oh no, how about six famous friends!

In video captured inside London's Hyde Park, Swift began singing along to her smash-hit single "Style." And one by one, a few famous faces began strutting their stuff in front of a sold-out crowd.

Kendall Jenner, Cara Delevingne, Gigi Hadid, Martha Hunt and Karlie Kloss treated the stage like a runway while showing off their unique fashion. Even tennis superstar Serena Williams joined in on the catwalk.

"Cool down after the @TaylorSwift concert with my BFF @Carowozniacki," Williams wrote on Instagram after the unique experience. Lance Bass and opener Ellie Goulding were also in attendance for Saturday's show.

The latest star-studded performance comes on the heels of another big week for Swift.

In addition to persuading Apple Music to have a "change of heart" regarding their streaming service, Swift announced that she would "happily" allow the company to feature her latest album.

The singer and boyfriend Calvin Harris were also crowned Forbes' highest-paid celebrity couple. The fancy titles, however, won't stop the "Bad Blood" crooner from her main focus which is putting on great shows for all her fans.

Her next stop in the United States is July 10 at New Jersey's MetLife Stadium. If you have tickets, we're insanely jealous.
