Throughout her 1989 World Tour, Taylor Swift has brought a Bad Blood music video's worth of celebs onstage with her.

Her audiences have been graced by such coolness luminaries as Cara Delevingne, Kendall Jenner, Martha Hunt, Serena Williams, Karlie Kloss, Gigi Hadid, Lily Aldridge, Hailee Steinfeld, Lena Dunham, the U.S. National Women's Soccer Team, Serayah, Lorde, Uzo Aduba, Mariska Hargitay, a shark... Who will be next in this long line of women and animal? Who should be? I have some opinions.

What are my credentials? I'm a full-time professional Taylor Swift Instagram reporter, and I care.
