Swift got into the Halloween spirit during her tour stop, channeling the Frozen snowman character Olaf for parts of the show. The highlight of the night came when the costumed Swift performed “Let It Go” with Idina Menzel.

“Frozen totally happened tonight,” Swift captioned a clip of the performance on Instagram. “And 55,000 people sang ‘Let it Go’ so loudly, it nearly took my breath away. Good times, @idinamenzel.”

In addition to Menzel, Swift invited singer Alessia Cara on stage to perform Cara’s hit “Here”.

“Sharing a stage with @alessiacara and @idinamenzel was the perfect way to end this amazing chapter,” Swift wrote on Twitter. “Thanks ladies ☃?”
