Taylor Swift looks fully nude in her new video, and the internet is so not ready for it.

Taylor Swift fans have joked they were “not ready for it” when the singer shared a preview of her new music video for Ready For It, in which she appears to be almost fully naked.

On Monday the 27-year-old US pop star unveiled a snippet from the video, which will be released in its entirety on Thursday, and which sees her in full futuristic mode and seemingly nude.

Swift posted three short clips on her Instagram page, and within one hour they had been viewed more than 2.5 million times in total.

In the teaser, set in a futuristic sci-fi universe, Swift walks down a corridor with a hood over her head before she is seen as a robot or cyborg-like being.

She seems to be unclothed with geometric lines of lights across her body, although some fans have suggested she is wearing a nude-coloured bodysuit.

Another segment shows Swift gazing into a floating, glowing orb, while another snippet sees her smashing through what looks like a glass cage.

Fans of the star took to Twitter to share their thoughts over the teaser, with many using the song’s title to joke they were not prepared for it.

One wrote: “I literally just closed my eyes and when i opened it Taylor Swift released the teaser for …Ready For It? music video. I WAS NOT READY FOR IT.”

Many fans were confused over Swift’s apparent nudity.

One asked: “Is she naked with editing or is it a bodysuit?? She had to know we’d be wondering from the trailer!”

Ready For It is the second single from Swift’s forthcoming studio album Reputation, which is set for release on November 10.

Swift dropped the album’s third track Gorgeous last week.
