【Lady Moon】

It's official: Taylor Swift is Lady Moon30, flirty, and thriving.

The singer celebrated her milestone birthday on Friday, and spent the night singing at iHeartRadio's 2019 Jingle Ball and celebrating with friends.

After her performance, radio host Elvis Duran came on stage to present Swift with a giant cat-covered birthday cake, and he asked all the fans in Madison Square Garden to sing her "Happy Birthday."

The cake has three cat faces on it, which likely signifies Swift's own cats: Benjamin Button, Olivia Benson, and Meredith Grey. Aww. Duran's three-tiered cat cake was gorgeous and genuinely impressive, but it wasn't Swift's onlycat cake this birthday.

On Saturday morning, the singer shared yet another cat cake, and though this one was smaller it was far more deranged.

The second cake once again featured three (very realistic looking) cats clawing their way out of a mess of flowers and frosting. The intention was sweet, but the reality is that this cake was sort of creepy! I mean, imagine cutting into that thing. And then EATINGit. Criminal!

Swift also posted a number of birthday photo booth shots that she took with friends at what sounds like her own holiday party.

"Honestly spending my 30th with the fans who have made my life what it is at jingle ball, then throwing the most aggressive holiday party known to womankind... I just.. seriously feel so lucky for you all and will spend forever trying to find ways to say thank you. *cries in Christmas tree*" Swift captioned one of Instagram albums.

Celebrities like Gigi Hadid, Jack Antonoff, Ryan Reynolds, Blake Lively, Cazzie David, Jonathan Van Ness, Antoni Porowski, and more can be seen in the photos.

It remains unclear whether any of these people ate a slice of cat cake, but we hope everyone had a good time.
