How do we know this *top secret* info?
Last Thursday, the 27-year-old singer reblogged a Tumblr post that read, “The little kid saying ‘Gorgeous’ at the beginning I think is my favourite part though Taylor…I mean IT’S JUST SO CUTE! Who is that????”
Taylor responded with: “300 people know," an obvious nod to the listening parties in London and Rhode Island where a few lucky fans got to listen to Reputation ahead of its release.
Rule #1 in how to make a song cuter: add the vocals of Serena van Der Wooden's daughter.
