If you thought Taylor Swift had befriended every young woman from here to Hollywood - you were wrong.
The 25-year-old superstar has revealed her blossoming friendship with actress Blake Lively, with whom she shared an exciting day on the Gold Coast at Warner Bros. Movie World.
The leggy, blonde duo closed down the theme park, snapping themselves enjoying its empty halls and posing with kangaroos.
"Yesterday was such an amazing day off," Taylor posted on her Instagram. "Roller coasters, kangaroos and LOLs with @blakelively."
The pair were enviously adorable, posting in-jokes on their social media accounts and just generally having a grand old time.
According to People, Lively, 28, is in Australia filming her new film, The Shallows.
The former Gossip Girl star is the latest addition to Taylor Swift's "squad", which includes other high-profile celebs like Lena Dunham, supermodel Gigi Hadid, and Kiwi songstress, Lorde.
Swift is in Oz performing her highly-praised '1989' concert tour to packed houses in Sydney, Brisbane, Adelaide and Melbourne.
The star has been trying to keep a low profile while Down Under and recently made headlines for having a Channel Seven reporter kicked off Hamilton Island, where she was celebrating her upcoming birthday with family and friends.
Swift will turn 26 on December 13.
