Taylor Swift marked her birthday on Instagram, by posting an adorable throwback photo of herself as a youngster, wearing a Little mermaid sweatshirt.
"Today I begin my 26th year of freaking out over stuff," Swift captioned the picture.
For her celebrations, Swift was joined by friends along with her mother Andrea, boyfriend Calvin Harris and DJ Snake at a party reportedly held at Apple executive Jimmy Iovine's Malibu home.
Also in attendance at the bash were Santa and Mrs Claus, who were on hand to hear guests' Christmas wishes and there were also live penguins and a snow-covered hill for sleighing.
Iovine's son Jamie shared a picture of himself alongside Swift and Harris on Instagram with the caption, "I was just adopted by @calvinharris and @taylorswift mom and dad are gonna show me the good life now.
