Taylor Swift has had one of the most successful tours in 2015. However, it's not just because of her sparkly outfits, elaborate sets and choreography. The hype around The 1989 World Tour has centered around the constant flow of celebrities who've made special appearances during her shows.

From her supermodel besties to her favorite artists and actors, Taylor has really run the gamut when it comes to who she welcomes to the stage. With such famous friends, it wasn't too surprising to see members of her "Bad Blood" squad at not one, but a number of her shows. That's what friend are for right?

She also highlighted some of the summer's biggest hit songs by inviting artists like Echosmith, OMI and Walk the Moon onstage to perform. But Taylor didn't just limit her guests to solely those of the musical variety: Athletes like Kobe Bryant and the U.S. Women's Soccer Team, who became the FIFA Women's World Cup champions this year, also celebrated their laurels onstage with the "Wildest Dreams" pop star.

The 1989 Tour isn't over yet, and we have yet to see who else Taylor will bring to the stage. Although some stars have passed on the opportunity to join Taylor for a rousing rendition of "Shake It Off," we're sure there are many others who'll be stopping by her show in the coming weeks. In the meantime, see the rundown of all the celebrities who've joined Taylor on tour in the gallery above.
