Taylor Swift [1] and Lorde [2] took their friendship to the next level this weekend! The budding besties made the requisite NYC trip, exploring the concrete jungle together in coordinated coats. The singers goofed around on a sidewalk Sunday, laughing and smiling as they posed for photos. From the looks of it, Taylor and Lorde were re-creating the iconic Jack and Rose moment in Titanic [3]. The getaway is also a work trip for Lorde, who is set to perform at the Roseland Ballroom in a short series of concerts. We last saw Taylor and Lorde together when they relaxed at the beach during a girls-only weekend [4]. With all the cute moments [5] over the past few months, it's easy to forget their friendship took off late last year [6]. Keep scrolling to see their NYC fun!
