Los Angeles, July 11 (IANS) Singer Katy Perry has addressed a rumour that she is related to fellow singer Taylor Swift. She has joked that they fight like cousins.

During an interview on a show, the mention came up how it has been reported on MyHeritage.com that she and Swift were ninth cousins, reports etonline.com.
Perry called the rumour "fan fic", and joked: "Well, we fight like cousins."

The pop star was, however, open to exploring whether she is actually related to Swift. "Wow, I''m going to have to ask her if this is true or if we should, like, get blood tests together or something," she quipped.

In June last year, Swift had talked about working things out with Perry after a long feud.
