The 25-year-old Grammy winner said the Florence and The Machine frontwoman "fascinates" her companions, reported People magazine.
"What sets Florence apart? Everything. Every time I've been around her, she is the most magnetic person in the room - surrounded by people who are fascinated by the idea of being near her," Swift said.
"But when she meets people, she pays them a warm compliment and immediately disarms them. There are very few people I've met in my life who are truly electric, and Florence is one of them," the "Blank Space" hitmaker added.
