Taylor Swift brought the North American leg of her 1989 tour to a close in Tampa, Florida Sunday night, and clearly saved the best of her special walk-on guests for last.
The 25-year-old pop star stunned fans by inviting Broadway icon Idina Menzel on stage for a duet of her massive hit “Let It Go” from Disney’s Frozen. Not before a costume change, of course.
Swfit, decked out in an Olaf costume, announced Menzel, who came out in full Elsa drag:

“Frozen totally happened tonight,” Swift wrote on Instagram. “And 55,000 people sang ‘Let It Go’ so loudly, it nearly took my breath away.”
