Katy Perry got quite the genealogical surprise when she called into the U.K.'s Capital FM on Friday (July 10).
During the chat, host Sian Welby presented a well-researched fan theory to the pop star: that she could be ninth cousins with none other than Taylor Swift. "Well, we fight like cousins," Perry quipped at first -- referencing the pair's famous "Bad Blood"-era feud -- before incredulously joking that the theory was nothing more than "fan fic."
However, the singer was stunned to discover Welby and her fellow hosts were being dead serious about the connection to her fellow superstar, which one fan apparently put together on the family history platform My Heritage. "Wow, I'm gonna have to ask her if this true, or if we should, like, get blood tests together...It's cool because you can just, like, spit in a tube." Perry said while wearing a bright yellow hoodie from her brand-new "Smile" merch line.
