After playing a pivotal role in the first music video that Taylor Swift released in support of The Tortured Poets Department, Post Malone opened up about what working with Swift was like. Swift’s new album dropped on Friday, just hours before she released the music video for her new song “Fortnight.” The song arrived as the first track on the surprise double album and included a featured credit for Post Malone. In addition to his contributions to the song, Post also appeared alongside Swift in the “Fortnight” music video, which Swift directed. On Saturday, Post shared a behind-the-scenes photo of himself sitting on a couch next to Swift. The rapper’s hands rested on an object in front of him as he looked directly into the camera. Meanwhile, Swift sat beside him while dressed in a black sweater and jeans, her head resting on one hand. “It’s once in a lifetime that someone like @taylorswift comes into this world,” Post wrote in his Instagram caption. “I am floored by your heart and your mind, and I am beyond honored to have been asked to help you with your journey ???? I love you so much. Thank you Tay ????.”
