Country star Taylor Swift celebrated her 25th birthday with Beyonce and Jay Z.
Swift, who reached the milestone last weekend, performed at New York City's Jingle Ball before carrying on the party at her apartment in Tribeca.
Alongside a photo of her posing with the 'Drunk in Love' hitmakers and Justin Timberlake, Sam Smith, Karlie Kloss and girl band HAIM, she wrote, "So this is being 25... #WHAT #bestbirthdayEVER. (sic)"
Swift was also joined at the party by Emma Roberts, Ansel Elgort, Kelly Osbourne, Nick Jonas and Chrissy Teigen as well as best friend Selena Gomez.
The singer shared a snap of her newly-manicured nails, which were decorated with two halves of a heart, each with a letter in: S and T.
