Katy Perry appeared via Zoom for an interview with London’s Capital FM on Friday, July 10th. She was there to talk about her new single ‘Smile’, but the Capital Breakfast hosts introduced Perry to the theory that she and Taylor Swift are actually distant relatives.

“Apparently you and Taylor Swift are ninth cousins. Is this right?” asked Capital’s Sian Welby. “Well we fight like cousins,” said an incredulous Perry before dismissing it as “fan fic.” But Welby’s co-host Roman Kemp urged Perry to take the theory seriously.

“I don’t know if it’s fiction, but someone has literally written a full thing,” he said. “It’s like, ‘This is real. Look, they’re linked like this.’ And they’ve done it on that MyHeritage site.”

Perry was evidently (if not a little melodramatically) gobsmacked. “Wow,” she said. “I’m going to have to ask her if this is true, or if we should get blood tests together.” Check it out here.

Perry and Swift’s relationship has been nothing if not volatile over the last decade. While they were initially pop star bosom buddies, things began to unravel after it was revealed that three dancers left Swift’s Red tour to join Perry’s Prism tour. Swift wrote the indignant revenge single ‘Bad Blood’ in response. But the pair have been on better terms in recent years, with Perry even appearing in the video for Swift’s 2019 single ‘You Need to Calm Down’.

‘Smile’ is the fourth single from Perry’s upcoming album of the same name, which is due for release on Friday, August 14th. It’s Perry’s first LP since the lukewarmly received Witness came out in 2017. The first single, ‘Never Really Over’, came out in May 2019. It was a chart success, landing at #15 in the US Billboard Hot 100 and #7 in the ARIA singles chart. ‘Harleys in Hawaii’ followed in October 2019 and ‘Daisies’ came out in May 2020.
