On Sunday, Taylor Swift turned 26, celebrating with a seasonally-appropriate Christmas-themed party held at Apple exec Jimmy Iovine's Malibu crib, according to E! Online. Swift attended with her mom Andrea Swift and DJ boyfriend Calvin Harris.
Other attendees were actual penguins, DJ Snake, Gwen Stefani and Blake Shelton, according to Hollywood Life.
Swift's 1989 World Tour ended on Dec. 12, just a day before her birthday bash. Speaking of her birth year and birthday, Swift recently applied to trademark the word "1989," although she already owns "Party like it's 1989," according to the Washington Post.
Social media quickly began to swirl with birthday tributes to Swift from her famous friends. Even more came after her star-studded party on Sunday.
On her birthday, Swift also gave fans a gift when she announced that a documentary of her tour, 1989 World Tour Live, will be released on Dec. 20.
