Taylor Swift steps out of her hotel in New York City on Friday afternoon (August 31).
Earlier in the day, the 22-year-old musician was spotted wearing a varsity jacket for a photo shoot.
During T‘s MTV First interview, she opened up about how her new single came to life.
“Well I wrote this song with Max Martin and Shellback, which didn’t hurt at all,” Taylor shared. “This actually happened. When we were in the middle of writing a different song and this guy walked into this studio randomly and he’s like, ‘I’m friends with your ex-boyfriend. I heard you guys are getting back together.’ But as soon as he left, I just started going on this rant. So Max said, ‘You seem really passionate about it. You should write a song about it.’ We just created this song in like 30 minutes. It came from a very real place and it came from a very spontaneous situation.”
