This year, Taylor had a handful of special guests during her tour, she didn't host her annual Fourth of July bash, and she only brought a few close friends to award shows, including her tour opener Camila Cabello. During Taylor's concert in Pasadena, CA, in May, Selena Gomez opened up about her longtime friendship with the singer when she made a surprise cameo. "The reason why she has been one of my best friends is because this person has never, ever judged a single decision I've made," she told the crowd. "But honestly, thank you from the bottom of my heart for supporting someone that I know that is the most beautiful, strong, independent woman I've ever met. So thank you for supporting my best friend." Honestly, 2018 only made us want to be BFFs with Taylor even more!
