Frozen fans, rejoice: Taylor Swift is one of you. In another absolutely brilliant collab, Idina Menzel joined the young singer on stage for a round of “Let it Go.”

Happy Halloween! Did you have fun? We’re sure you did. But however much fun you had, it can’t possibly compete with getting to sing “Let it Go” with Queen Elsa herself, while dressed up like Olaf the snowman.

Taylor Swift did just that, because she can, and the result will melt even the coldest of hearts:

Amazingly, Taylor herself wasn’t even singing in the short clip of the song she tweeted out, but let Idina Menzel — whose Halloween costume was her Frozen character Elsa — steal the spotlight. Rather than singing, she danced around like Olaf, a spectacular sight on its own.

We’ve combed YouTube for the best fan recording of the “Let it Go” performance, and it seems to be this one by Musicb0x1:

After Menzel opens the number, the costumes come off (unfortunately, the dressed-up version was much more fun) and Taylor gets her solo — and we don’t blame her. Who could resist being Elsa for a night?

Luckily for Frozen fans, there’s much more magic coming. Not only is a sequel in the works, but there is a musical coming to Disneyland in 2016, and later to Broadway!

Fans of Taylor Swift will also want to make sure they check out her music video for “Wildest Dreams,” which co-stars Scott Eastwood.
