VIDEO: Taylor Swift Performs New Song 'Never Grow Up' for First Time on Tour

At her August 15th 1989 World Tour stop in Santa Clara, Calif., Taylor Swift performed her new song, "Never Grow Up" for the first time on the tour and dedicated it to her new godson, Leo Thames, son of Swift's close friend Jaime King.

Shared the pop star, "I wrote it when I was like 18 or 19, but my friend just had a baby and she made me godmother of it and I was holding this little baby the other night, and I was just thinking differently. When you're holding onto something that's so innocent and so perfect and has no idea what's coming for it with the world. The world is going to throw so many things at you as we grow up." Watch the performance below!
