"We were front row watching watching Ariana Grande [at the American Music Awards], loving her performance. We're both pretty animated when we're watching other artists," Taylor told Rolling Stone.
"At the end of her performance, she did some dance move that was so sexy and so cool, and at the same time, Sam and I both screamed out "YAS [GIRL] YAS!!" and then looked at each other and died laughing. I had this feeling that we'll be friends for life."
