Taylor Swift's new album, "The Life of a Showgirl," will be released this fall. The tracklist includes 12 songs and a duet with Sabrina Carpenter.

Oh, and while Swift says that The Life of a Showgirl was made with just her, Max Martin and Shellback, that’s not quite true. The title track, which closes the album, features Sabrina Carpenter, teeing up the possibility of a pop collaboration for the ages.
