Taylor Swift Was Olaf For Halloween & That's Not Even The Best Part — VIDEO

To be honest, I don't know how Taylor Swift does it. She's been traveling around the world as part of her 1989 World Tour for what feels like forever now, though it actually only began in May. Maybe it's just because her shows are so jam-packed with big numbers and special guests that I can't imagine doing that every night for months on end — just seeing her Instagram posts about it make me feel tired. (Then again, I am lazy, so maybe that explains it.) In any case, she certainly knows how to put on a show and had no intentions of slowing down for Saturday night's show in Tampa, Florida. That's right: Swift celebrated Halloween by dressing up as Olaf from Frozen and singing "Let It Go" live with the movie's star, Idina Menzel.

Admittedly, I'm not as crazy about Frozen as the rest of the world seems to be, but I can't deny that it's a great story and a lot of fun. Also, who could resist Swift in an Olaf costume? As she walked on stage to begin singing "Style", something was noticeably different about the her. Oh yeah, it must've been the giant snowman costume, as well as the fact that her background singers were dressed as reindeer.

As if things could get any better, Swift then lamented to the audience about the fact that Idina Menzel wasn't on hand to celebrate Frozen with everyone. Except she was, and she came up through the floor dressed as Elsa and ready to duet "Let It Go" with Swift. Yeah, it happened, and it was incredible, and I'm totally jealous that I wasn't there to see it, to be honest.

Pretty mind-blowing, right? But given that Tampa was the last stop on the U.S. leg of Swift's 1989 World Tour, it made sense that the singer would go out with a major bang — and I think this more than counts. It's safe to say that Swift wins Halloween this year, right?
