Eagle-eyed Tay fans have noticed that there was more to this post than meets the eye, namely a few Taylor-centric references.
As die-hard Swiftys will know, Taylor's fave numero is 13 (duh!).
Take another look at the IG upload, can you spot the shoutouts to 13?
First of all, the pic was ~conveniently~ posted on July 13 - not 12, 14 or 15. 13!
Also, the caption reads: "Sultry pop magic from this dreamy almost-birthday-girl," followed by, you guessed it, 13 applause hands.
Mhmm, Tay knows what she's doing!
And that's not all, either. Taylor has been slipping 13 references in all her squad shoutouts lately.
When Tay uploaded snaps of besties Haim, Lorde and Ed Sheeran's singles, she made sure to pause the track at 13 seconds.
THIS WOMAN IS A GENIUS!
Or an OCD nut... you decide.
