Taylor Swift says her dad is her biggest fan

London: Singer Taylor Swift says her father is her biggest fan and supports her professionally.

"My dad (Scott Kingsley Swift) is adorably optimistic, positive, pie-in-the-sky. He thinks every new song I write is my best. He sells T-shirts at my merchandise stands and hands out guitar picks to fans," contactmusic.com quoted her as saying. Swift also revealed how she takes elements of her mother`s personality into her onstage persona. "Mom is a planner, an organiser. She`s very strong and practical. She`s the person that`ll tell me if I ever start to change my personality. The balance of the two of them created my personality," she said. IANS
