A teaser released earlier this week caused a frenzy among fans and has already stirred up controversy thanks to Swift's risque bodysuit and apparent influences by the film adaptation of Ghost In The Shell.
Here's everything we know about the video so far, including when to expect its release and who's involved.
What's the song?
"... Ready For It?" was released as a digital download after being teased as part of a US broadcaster's sports coverage. It was written by Swift with Max Martin, Ali Payami and Shellback.
When will the video be released?
Not much has been revealed apart from that the video will be released on "Thursday night" - Thursday 27 October.
Swift's most recent video, for "Look What You Made Me Do", was released at 11.30pm ET time, but if Swift wants to catch her UK audience as well it could drop early evening in America for a midnight UK release time (7pm ET).
In the teaser, Swift appears to star as a sexy robot. The music video is directed by Joseph Kahn, who has worked with Swift on a number of other music videos including the recent "Look What You Made Me Do", "Wildest Dreams" and "Blank Space".
As well as Swift, Kahn has directed videos for some of the biggest pop stars in the world including Britney Spears, Maroon 5, Mariah Carey and Christina Aguilera.
From the teaser, it looks as though Swift and Kahn have been inspired by the recent spate of sci-fi films such as Ghost In The Shell and Blade Runner 2049.
What should we expect?
There are obviously already hundreds of fan theories around the teaser. Many speculate that Taylor is fighting the old version of herself in the video. They think the lightning bolt could be a dig at her ex-boyfriend Calvin Harris and his track "This Is What You Came For" ft Rihanna, which she claimed songwriting credit for.
When is the album released?
reputation is due to drop on 10 November 2017.
