Nothing like exploring the great outdoors with your bestie.
Wearing matching white Keds (adorable!), Taylor and Ella wore comfy sweatshirts. Taylor sported adorable pigtails, a gray sweater and tan shorts, while Ella decided to rock some jean shorts and a matching denim bucket hat.
The BFFs must have worked up a sweat, since they shed their layers, exposing Taylor in a v-neck T-shirt and Lorde in a Calvin Klein crop top, showing off her abs.
What do you think they talked about on their hike? The fact that they looked positively stunning at the Golden Globes after party? Or maybe they were discussing a collaboration for Lorde's "amazing" upcoming album? Or maybe they were just complimenting each other on how awesome they are.
