Taylor Swift’s 1989 Tour has been getting a lot of attention because of the special guests she brings out during each show. In recent months, she’s shared the stage with The Weeknd, Fetty Wap, Wiz Khalifa and more. But last night’s stop in St. Louis might have been the best one.

Nelly and Swift have actually performed together on tour a lot. In 2011, he joined her on the Speak Now Tour in Houston, and in 2013, he was with her for the Red Tour. This appearance makes it three for three.

When Swift brought out Nelly, they performed his new song, “The Fix.” After that, he was joined by Haim for a rendition of “Hot in Herre.” What was pretty awesome about this performance was that they created a fun dance routine the day before.

If you weren't there to witness it, you can watch some videos from Swift and Nelly’s social media accounts. Who do you think Swift will bring out next?
