Taylor Swift thrilled fans with the release of her new album “The Tortured Poets Department” on April 19, which turned out to be a double album. The album’s first single is “Fortnight,” a duet with Post Malone.

While fans are just getting their feet wet with the album and this collaboration, the pair actually has a history that predates this effort. Read on to learn about their relationship.

“‘Better Now’ is so insane. I’m so jealous of that song, that hook,” she told him.

“And I was like, ‘What?’ That’s f—— crazy, you’re a great f—— songwriter! Thank you so very much,’” he told Howard Stern in 2023 about that encounter.

Malone said there are “so many beautiful artists in the world” and that it was “really special” for Swift to acknowledge his work during their brief interaction.

“That was a really cool moment, and it was very inspiring,” he said.

April 2024: Taylor Swift and Post Malone collab on ‘Fortnight’ song and music video

On April 18, the day before her “The Tortured Poets Department” album dropped, Swift teased her and Malone’s song, “Fortnight,” while sharing what it was like to work with the “Sunflower” artist.

“The first single from The Tortured Poets Department is…………. Fortnight featuring @postmalone I’ve been such a huge fan of Post because of the writer he is, his musical experimentation and those melodies he creates that just stick in your head forever,” the “Love Story” singer penned.

“I got to witness that magic come to life firsthand when we worked together on Fortnight. Honestly can’t wait for you guys to hear this song at Midnight TONIGHT and see the video at 8pm ET TOMORROW,” Swift continued.

“Fortnight” dropped April 19, along with the music video, which featured Malone and Swift as lovers in a sort of experimental mental institution.

“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.”
