Los Angeles: Singer Katy Perry is reportedly planning to release a track aimed at Taylor Swift as a response to Bad Blood, which is widely believed to be about their feud.

UK newspaper The Sun reports the 30-year-old singer has enlisted American DJ and music producer Diplo for the song, Crocodile Tears.

“Katy knew Diplo would be just the man to produce Crocodile Tears for her and has now registered it. So far she’s been very restrained with what she’s said about Taylor in public, but is now ready to put her side across via the song — which is all about being fake,” said a source.

The source is not sure if the song will make the cut for Perry’s next album or not, but the singer is said to be “keen for fans to hear it”.

Fans learned of the feud last year after Swift said in a Rolling Stone interview that Bad Blood is about a fellow female entertainer who tried to sabotage her tour by stealing her dancers.

The 25-year-old refused to specifically name anyone, but it’s understood she’s talking about Perry.
