One of the most talked-about facets of Taylor Swift's "1989" tour is the 1,900 or so celebrity guests who've shown up. OK, maybe it hasn't been that many, but it's been a lot — at least one every night in a majority of the cities.
Most have some kind of local connection. Some, such as Julia Roberts and the U.S. women's soccer champions, just get up and wave. All of the guest musicians, however, have performed one of their own songs with her. Here's a sample guest list from some of the cities so far:
Los Angeles: Justin Timberlake, Natalie Maines, Mary J. Blige, Alanis Morissette, John Legend, Beck, St. Vincent, Selena Gomez, Ellen DeGeneres, Lisa Kudrow.
Santa Clara, Calif.: Joan Baez, Julia Roberts, Fifth Harmony.
Seattle: Fetty Wap, Sean Mendes, Nico and Vinz, Ciara.
Chicago: Sam Hunt, Andy Grammer, "Empire's" Serayah McNeill.
Washington, D.C.: Lorde, Jason Derulo.
East Rutherford, N.J.: U.S. women's soccer team, Nick Jonas, the Weeknd, "Girls" cast, Haim.
