Lorde has officially kissed her teen’s goodbye. The “Royals” singer turned 20 on Monday and shared an intimate message on her Facebook about what this important birthday means to her. “If I’m being real with myself, in some ways I stopped feeling like a teenager a while ago… Sometime in the last year or so, part of me crossed over.”

But her good friend Taylor Swift made sure she crossed over in style, throwing the native New Zealander an intimate party at ZZ’s Clam Bar in New York City according to TMZ. Lena Dunham, Karlie Kloss, and Aziz Ansari were also in attendance for the festivities. Tay Tay posted a cute birthday message to Lorde, real name Ella Marija Lani Yelich-O’Connor, before they both flooded Instagram with snaps of the festivities. We’re not jealous or anything.
