A host of superstars including Beyonce, Jay Z and Justin Timberlake headed to Taylor Swift’s New York apartment on Friday to celebrate her 25th birthday.
The Shake It Off hitmaker kickstarted her day of celebrations by picking up the Woman of the Year accolade at the Billboard Women In Music luncheon, where Icon of the Year honouree Aretha Franklin serenaded her with a rendition of Happy Birthday.
She then headed to radio station Z100's annual Jingle Ball in the Big Apple gig, where she performed, before heading back to her luxury pad to host her star-studded party.
Swift decided not to change out of her plaid two-piece stage costume for the bash, where guests enjoyed pizza and Japanese food while wearing novelty headwear and posing for pictures.
Snaps from the party show Beyonce, Jay Z and Timberlake joining Swift, singer Sam Smith, model Karlie Kloss and sibling rockers Haim in a variety of comedy poses. In one image, Timberlake is shown wearing a hat, shaped like an emoticon, over his face, while Beyonce dons furry antlers.
Other guests at the event included Selena Gomez, Nick Jonas, model Chrissy Teigen, actors Ansel Elgort and Jaime King, Kelly Osbourne and Charli XCX.
Following the party, Swift took to Twitter.com to write, "I just want to thank anyone who wished me happiness today. You're my friend. These are my friends. And I'm so lucky."
