Taylor Swift sent an indirect message to LeBron James on Saturday night:
Not so fast, buddy!
Just as the editors of The Hollywood Gossip were set to crown James as the winner of Halloween 2015, Swift stepped to the microphone in Tampa, Florida.
And while we've seen plenty of the superstar surprising concert attendees with special guests, we've never seen anything like this before.
Because it features Idina Menzel, dressed as Elsa and belting out the smash hit song "Let It Go" from Frozen? Not quiet, although the following video does feature Idina Menzel dressed as Elsa.
But it also features Swift joining Menzel on the track... while dressed as Olaf!
(For the three people out there who have not seen Frozen, Olaf is the hilarious snowman sidekick in the film.)
About halfway through the performance, Menzel and Swift shed their costumes and went straight on sexy instead of goofy, with Swift wearing her beloved silver sparkly mini dress and Menzel rocking a black bustier with black leggings and heels.
"Frozen totally happened tonight," Swift captioned one picture with Menzel on Instagram.
"And 55,000 people sang 'Let it Go' so loudly, it nearly took my breath away. Good times, @idinamenzel."
Menzel chimed in herself via social media, remarking on how this experience was slightly different than her typical routines on Broadway.
"Thank you @taylorswift! That was definitely an out of body experience. Or out of Elsa's body experience! #1989tourtampa."
Amazing stuff. Watch now:
