New York, New York - Taylor Swift has given fans a peek behind the curtain by dropping new snaps from her lavish birthday bash.

Later snaps feature Tay posing with Gigi Hadid, Jack Antonoff, and Sabrina Carpenter, with all being captured with her signature purple filter, of course!

Notably absent from the festivities was Taylor's boyfriend, Travis Kelce, who was unable to attend due to mandatory practice with the Kansas City Chiefs.

Insiders have revealed that the pair did get to commemorate her milestone year together, opting for an earlier celebration while Taylor was in town for Sunday's Chiefs-Bills game.
