Lorde turned 20 yesterday and it was *literally* all she could think about.

"Tomorrow I turn 20, and it's all I've been able to think about for days," she wrote in an emotional Facebook post about her birthday, her new music, and the many ~feels~ she was having about her impending adulthood.

Looks like Lorde's 20th wasn't just a Big Deal to her. It was also a Big Deal to her BFF, Taylor Swift, who, let's be honest, makes a Big Deal out of all of her friends' most special days (but that's probably why approximately one million famous people want to be her best friend).

Taylor threw Lorde (or Ella, as Taylor nonchalantly calls her all over social media) an epic party.
