Once again, Taylor made her Swifties become a detective as she released a hint for her upcoming album Red Taylor’s version.

Taylor Swift is apparently bringing in Phoebe Bridgers as a guest for her upcoming “Red (Taylor’s Version)” album — not according to any press release, but according to a word puzzle the superstar put up on social media Thursday evening.

Chris Stapleton and Ed Sheeran also appear to be confirmed as official features. Sheeran’s participation was already known — as he appeared on the original “Red” album, and recently said in an interview he’d re-recorded his duet part — but Stapleton joins Bridgers in the surprise project.

Some of the clues were tougher than the rest for Swifties to immediately decipher. But Bridgers’ name? Swift didn’t make that too much of a challenge for her fans. When you take the entire sequence of lines of letters that appear in the video clip and stack them top to bottom, the letters in “Phoebe” line up in the left hand column. Even more obviously, “Bridgers” runs left to right on the next-to-bottom line.

“Red (Taylor’s Version)” was announced in June as set to be released on Nov. 19 this. Until now, the only information Swift has released about it is that it will include 30 songs, and that it would include a 10-minute song, presumably the fabled 10-minute version of everyone’s favorite “All Too Well.”

Just in case, there was any doubt about that latter track, the puzzle does include all the words in “All Too Well Ten Minute Version.”

A CD version of the upcoming set went up for pre-order simultaneously with the release of the word puzzle; promised amid the packaging is lyrics for nine previously unrecorded Vault tracks.

Also Ed Sheeran, already known to be participating for their single Everything Has Changed, also shows up in the crossword.
