Taylor Swift just can’t let go of “Let It Go.”
The mega-watt pop star combined her Saturday performance in Tampa Bay, Florida, with Halloween when she invited Idina Menzel onstage for a costumed rendition of her hit song from Frozen.
Menzel, 44, dressed as Elsa, her character from the film, while Swift, 25, dressed as Olaf, the snowman (and her dancers dressed as reindeer).
The stadium-sized singalong didn’t end there, however – thanks to a surprising quick-change.

Of course, the crowd didn’t stop singing just because Swift and Menzel did.
Swift’s 1989 world tour, which wrapped in America on Saturday and now heads to Singapore, China and Australia, added Menzel to its long list of celebrity guests.
