Things got extra hot on tour for Taylor Swift thanks to her latest surprise guests.

During her show in St. Louis on Tuesday the pop star was joined on stage by none other than Nelly, the man who made bandages on cheeks a thing, and the guy who brought us the club staple, “Hot in Herre.” Oh, and Swift’s besties Haim were there too. A strange combo, but somehow it worked.

Swift shared a few Instagram videos of herself and the Haim girls doing a choreographed dance (which they apparently made up in the dressing room) to the 2002 jam while Nelly rapped the lyrics in front of them. They also provided the breathy female backing vocals. There’s a lot of sass going on, and Nelly is wearing jorts. Just thought we’d point that out for you.

We don’t know about you, but we think this is one of Swift’s best 1989 Tour collaborations. She can probably just drop the mic and be done with them now, right?
