"It would be weird to not include my friends. These are the people who helped me get to this point where I could make this album. We had some of the most amazing memories just around this tour... It actually became a way for us to all get together when we're all really busy. We'd all just be, 'Alright, meeting up in London, Hyde Park show, let's do this!'" Superstar Taylor Swift enjoyed mixing business with pleasure when friends like models Gigi Hadid, Kendall Jenner and Lily Aldridge joined her on various dates of her 1989 World Tour, which she has just wrapped up in Australia.
