Olivia Rodrigo went all out to celebrate turning 21!

On Tuesday, the "Vampire" singer marked the milestone birthday by taking to Instagram to share multiple celebratory snaps — including one showing her posing next to a "spill ur guts" cake.

Rodrigo has been busy rehearsing for her upcoming Guts World Tour, which kicks off on Friday in Palm Springs, California at Acrisure Arena. Her album of the same name was released in September 2023.

Rodrigo's birthday cake featured a heart-shaped middle layer, as well as a top layer that had her album name written on it with black and red icing. It was made by Duff Goldman's bakery Charm City Cakes, which posted a full-length photo of the incredible creation.

Another photo showed Rodrigo sitting among balloons while eating cake, while a video captured the moment she jumped up and down when she was presented with her special cake.

The musician also posted a throwback snap of herself as a child wearing a handmade birthday hat.
