In the past year, Taylor Swift gave fans Folklore, its sister project Evermore and revealed that she’s re-recording her first six albums in an effort to control her own masters. But she’s not done with the treats yet.

Good Morning America revealed in a tweet on Wednesday (Feb. 10) that the superstar will be making a “surprise announcement” on Thursday’s episode, which airs at 7 a.m. on ABC. The accompanying 10-second teaser didn’t reveal any additional information, featuring only an acoustic guitar instrumental.

Swifties on Twitter immediately began speculating what the big surprise could be, with the most popular theory being the release of Swift’s re-recorded Fearless cut, “Love Story,” just in time for Valentine’s Day.

Swift first teased the new version of “Love Story” in December, with a snippet featured in an ad for dating site Match written by Ryan Reynolds.

“Okay so while my new re-records are NOT done, my friend @VancityReynolds asked me if he could use a snippet of one for a LOLsome commercial he wrote so…here’s a sneak peak of ‘Love Story’!” she tweeted at the time.
