A cryptic countdown clock appeared on the singer’s website around midnight ET on Friday counting down to April 26.
That’s 13 days from now. 13 is T-Swift’s lucky number.
Adding to the mystery, Swift also changed her Twitter profile picture to the same pearly background on her website and posted a photo of a pink heart made up of sparkling gems.
This isn’t the first time Swift has sent fans into a frenzy.
But while new music is a likely theory, it could also be something else entirely.
“I make countdowns for things I’m excited about,” she wrote. “When I’ve gone through dark, low times, I’ve always found a tiny bit of relief and hope in getting a countdown app (they’re free) and adding things I’m looking forward to.”
