Katy Perry and Taylor Swift were rivals once, but now it appears they’re related.

Researchers at MyHeritage.com investigated the familial connections between the two stars and discovered that they are, in fact, ninth cousins.

During her appearance on Capital FM’s Capital Breakfast on Friday, Katy was informed of the news.

“Well, we fight like cousins,” she joked.

Katy added, “Wow, I’m going to have to ask her if this is true or if we should, like, get blood tests together or something.”

The two officially buried the hatchet last year after a years-spanning feud. Katy appeared as the burger to Taylor’s fries in Taylor’s video for “You Need to Calm Down.”

Katy on Friday released her new single, “Smile,” the title track off her upcoming album.
