The latest album of pop superstar Taylor Swift, "Reputation," will not be released until Friday, but it has already sold over 400,000 copies in pre-sales.

The singer's sixth album has also almost doubled the pre-sales numbers posted by her previous album, "1989," which was released in 2014. This is a very positive indication for "Reputation," as "1989" went on to become the fastest-selling album in more than a decade.

Target, one of the sites where pre-order for the album is available, has confirmed that "Reputation" has posted its largest music pre-sale of all time.

While the album has yet to be released, Swift has already released four singles off of it. The latest one, titled "Call It What You Want," was released on Friday. It follows "Look What You Made Me Do," which was released last August, "...Ready for it?" and "Gorgeous."

"Call It What You Want" is considered by many as the most personal of the released songs from the album and is said to have been inspired by Swift's current boyfriend, Joe Alwyn. The British actor is described on the track as "fit like a daydream."

Last week, the singer released the music video for "...Ready of it?" The dark, futuristic theme of the video looked like it was taken straight from the "Blade Runner" movie. In it, she squares off against a cyborg version of herself. The 27-year-old singer also appears to go naked in the video, which earned the ire of some of her critics.

This prompted Swift to post a video on Instagram in response to the criticism. "It truly warms my heart that [people] had so much to say about this body suit," she said, before getting the suit and showing how unrevealing it actually was.

"Reputation" will be released on Nov. 10. It is available on Amazon, iTunes, Target, Walmart, and Swift's website.
