Katy Perry had a hilarious reaction to the rumors that she and Taylor Swift are related.

During a recent interview on "Capital Breakfast with Roman Kemp," co-host Sian Welby said she had "gone deep into some Katy Perry fandom" and had come across the rumor that Katy and Taylor were "ninth cousins.".

"Well, we fight like cousins," quipped Katy, who famously ended her feud with Taylor last year.

Back in June of 2019, the global icons confirmed their feud was officially over after Katy appeared in Taylor's music video for "You Need to Calm Down.".

"It's like, we have so much in common there's probably only 10 people in the world that have the same things in common I was like, 'We should really be friends over that and share our strengths and our weaknesses and our challenges."
