Are Taylor Swift (30, "The Man") and Katy Perry (35, "Smile") cousins? At least that's what a bizarre fan theory claims on the net, to which the pregnant Perry is now contributing in a radio broadcast "Capital FM" responded. According to the theory, the two singers should be ninth-degree cousins - Perry then says "Well, we argue like cousins!" and describes the theory as "fan fiction".
She would find it "amazing" that someone has documented the family history of both singers so extensively. "Wow, I have to ask her if that's true. If so, we should do a DNA test together," said the singer. "If we both spit into a tube together, it would be good entertainment." So far, the two singers have only been in the press together because they had argued with each other for years.
