Taylor Swift Plays Big Sis for Lorde's 20th Birthday Party

Lorde has officially made it out of her teens, and she did it with BFF Taylor Swift showing her how to milk paparazzi camera shots like a 20-something "it" girl should.

Lorde took a dive into ZZ's Clam Bar in NYC Monday night with Taylor, Karlie Kloss, Jack Antonoff and Lena Dunham along to celebrate her big 2-0.

Everyone looked great, but the New Zealand pop star was the clear knockout.
