Katy Perry and Taylor Swift Are Cousins.

Katy Perry Finds Out She's Taylor Swift's Cousin

Katy’s new baby possibly has a famous aunt. During a radio interview, Katy Perry was told that she is Taylor Swift’s ninth cousin. "Well, we fight like cousins," joked Katy Perry, although she didn’t know anything about the possible relation, but considered getting a DNA test. Rumors have swirled about Perry and Swift working together since Perry extended an actual olive branch to the “Lover” singer in 2018 after they had been beefing for years stemming from background dancers that danced for both artist’s tours.
