Lorde has racked up the air miles to make a surprise appearance on stage with Taylor Swift in the US as part of her 1989 tour.
The Kiwi singer joined Swift as the special guest at her Washington DC show, where the pair performed Lorde's biggest hit Royals.
Swift had promised the crowd a "really good surprise" if they "maintained their awesomeness".
"Hint number one: this artist flew 19 hours from her hometown to be here with you." Lorde was then introduced by Swift as "one of my best friends in the entire world". They sang the song together, including lines like, "We'll enjoy being queens". The friendship between Lorde and Swift dates back to 2013. Initially, Lorde criticised Swift as being a poor role model for young girls, describing her as "so flawless, and so unattainable". Lorde later apologised for her comments and clarified them further on Tumblr. The singers later put any rumours of a feud to rest when they were spotted dining together. They've been close friends ever since.
Lorde recently praised Swift for bringing her into "this amazing world of supportive female friendship" in an interview in Dazed magazine with Girls star Lena Dunham.
