Taylor Swift & Selena Gomez Deliver The Duet We’ve Been Waiting For

Taylor Swift hasn't skimped when it's come to bringing musical guests on stage during her 1989 tour. John Legend, Beck, St. Vincent, Mary J. Blige, Natalie Maines, and Alanis Morissette are just a handful of the stars who've joined Swift over the past week. Those guys are hard to top, but in terms of Swift-level fandom, well, they're no Selena Gomez. Swift reunited with her O.G. bestie during last night's concert in Los Angeles. Gomez took the stage in a black bodysuit that echoed her pal's white version, then led the pair in a duet to her song "Good For You." We were hoping they'd bust out the "Bad Blood" fight sequence, but no such luck.

Gomez wasn't the only guest star of the night. Swift brought Lisa Kudrow on stage for a performance of "Smelly Cat" of Friends sitcom fame, then teamed up with Justin Timberlake for a duet to "Mirrors." It was all very epic, folks. Can't wait to see who Swift recruits next. Would a remix with boyfriend Calvin Harris be out of the question?
