The U.S. leg of Taylor Swift’s monumental 1989 Tour came to end over the weekend. Of course, Swift had some surprises up her sleeve for the last tour stop in Tampa, FL.

For those of you keeping track, she’s consistently brought out a special guest that ties with the city she’s in. While Alessia Cara and Idina Menzel aren’t from Tampa, this was a huge moment for the crowd celebrating Halloween with Swift.

Swift also indulged in the holiday by dressed up as Olaf (the friendly snowman) from Frozen. Since there was a Frozen theme for this show, she teased another big guest: Idina Menzel. They sang “Let It Go,” and it was amazing.
