Taylor Swift and Lorde have been BFFs for some time now.

And while the 1989 superstar hasn't been too active on social media as of late, she did make a rare cameo again today (Nov. 7) to wish one of her closest #squad besties a very happy birthday — complete with a hand-crafted card and an amusing anecdote.

"Thank you for the music you make, the advice you give, the thoughts you provoke, and the way you've made my life more beautiful since the first day we met up in New York and ate burgers on a park bench and got attacked by squirrels," Taylor wrote. "I. Love. You. So. Much. Ella."

On her end, Lorde posted a thoughtful update on Facebook about turning 20 years old today, complete with news of her second studio album.
