We decided to do that [having friends as special guest on 1989 World Tour] because theres a song called ‘Style’ where the performance in the show is actually more of a runway, you have the dancers strutting down the runway. Like a lot of my friends are really great runway models and that’s their job. And they come out to the shows and I know my fans would love to see them… I wonder if we could have them walk it like a runway show. Cara did it, Martha Hunt did it, Gigi Hadid did it, this great actress from Law and Order Mariska Hargitay did it. And I just want to keep it up, I think it’s fun to have people pop up and make special guest appearances on the tour even if they’re not musicians.
