Jack Antonoff recently talked about collaborating with Taylor Swift throughout the years.

Jack served as the producer of Taylor's several albums, including 1989, Reputation, Lover, Folklore, and Midnights. 

He also took part as a producer of the vault tracks of Taylor's re-recordings.

"[She was like] you produce this. That relationship goes on and on and we pushed each other endlessly," he said about his collaboration with Taylor in an interview with Sunday Sitdown of The Today Show.

On why he thinks he works well with Taylor, Jack said that the "Anti-Hero" singer has always believed in him.

"I could quantify our relationship in very reductive ways about the things we agree on, the sounds we like, but the truth is we've just grown together. I mean, she's put an amazing amount of belief in me, and it's powerful," he remarked.

In the same interview, Jack also discussed one of their most popular collaborations which is "Getaway Car" from Reputation.

The behind-the-scenes clip of the song went viral on social media after it got featured in Taylor's Netflix documentary Miss Americana.

"That video is popular for the perfect reason. That is the only time in my life, from the million hours I’ve spent in studios that a camera was ever on ... when magic actually happened," Jack said. 

"And she just had her iPhone on for whatever reason. And I think that’s why that video became so popular because it was real," he added. 

"It was just a real moment, and I don’t know why her phone was on, but thank God it was," he continued. 

Jack and Taylor's latest collaboration, 1989 (Taylor's Version), came out on October 27.

The re-released album became an instant hit, which had the biggest debut on Spotify to date in 2023.

On October 30, Taylor penned a message dedicated to Jack as she promoted the song "Sweeter Than Fiction" for 1989 (Taylor's Version), which was the first song they collaborated on.

"'There you’ll stand ten feet tall, I will say ‘I knew it all along.'' This song has always made me think of my friend Jack. It was the first song we made together and watching him challenge himself and make beautiful art over the years has been the thrill of a lifetime," Taylor said.

She added: "How can he be 6 years older than me and also somehow still be my precocious young son? We may never know. 'Sweeter Than Fiction (My Version)' is now available exclusively at Target on Tangerine vinyl 🍊."
