People always believed that Taylor Swift was magical, but now there is proof! The 25-year-old singer just posted a video to Twitter of a six month old baby named Rosie , who only stops crying when she hears “ Blank Space .” Then, the song is turned off, and the baby starts crying again. Swift saw the video and sent out a tweet: THIS IS THE BEST THING I HAVE EVER SEEN.This will come in handy for Swift, who was just named the godmother of BFF Jaime King ‘s second child !
