Is there anything Taylor Swift won’t do on Instagram?? She’s given love advice to her fans around the world, publicly wish her besties a happy birthday, and now she’s leaving mysterious clues on the photo sharing app? Could it be for a new single? The singer recently shared a photo with the caption “So, here’s your first clue…” What could it possibly mean?! If she’s planning on releasing a new single on the 18th of this month, that’s definitely before her VMAs performance.
