The 43-year-old "Livin' la Vida Loca" hitmaker said Swift, 25, asked him to perform together and he was immediately game for it, reported People magazine.
"She's a sweetheart! She said, "Let's do it!" And I'm like, "I'm ready!" First of all, I always wanted to see her show. I was in Miami, and she opened the door, and I said, "Of course, let's have fun," Martin said.
The Puerto Rican singer said the "Bad Blood" hitmaker is sexy and cool and it was very special for him to perform with her.
