Taylor Swift's new single is called Ready For It - but it seems that many of her fans were not.
Because in the US star's video for the track, she appears to be naked.
One fan asked on Twitter: "Is she naked with editing or is it a bodysuit??"
Another commented: "I wasn't ready for it! Now my heart is racing and my head can't stop thinking about how amazing and powerful this video is."
In a short clip posted on Instagram, Swift initially walks down a corridor with a hood over her head.
The video is set in a futuristic sci-fi universe. Once the hood is gone she appears to be playing a robot or cyborg.
Geometric lines crisscross the 27-year-old's body.
One fan said they were "freaking out", describing the video as a "mix of Star Wars and Blade Runner 2049".
Another said: "I'm still attempting to digest the image of Taylor Swift in a nude body suit for her new video omg."
Anyone watching Swift's career closely may be a little surprised after watching the clip.
In 2014, she told the US edition of Glamour magazine she had no desire to strip off.
"I find it relatively easy to keep my clothes on," she said, "because I don't really feel like taking them off.
"It's not an urge I have. For me risky is revealing what really happened in my life through music.
"Risky is writing confessional songs and telling the true story about a person with enough details so everyone knows who that person is.
"That's putting myself out there, maybe even more than taking my shirt off."
Ready For It is the second single from Swift's new album Reputation, due to be released on 10 November.
