Katy Perry is reportedly planning to release a song to take a dig at Taylor Swift. According to a report in the Sun, the Roar singer is gearing up to record a song called Crocodile Tears with Diplo.

"Katy knew Diplo would be just the man to produce Crocodile Tears for her and has now registered it," a source said, as quoted by the Mirror.

"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," the insider added. "It isn't yet known whether it would be released as a one-off or as part of Katy's fourth album, but she is keen for fans to hear it."

The 25-year-old Red singer and Perry were best friends for a long time before things got bad between the two. In an interview with Rolling Stone magazine, Swift revealed that the song Bad Blood from 1989 album, is about a former friend. The two apparently fought over backup dancers.

Perry later took a dig at Swift during the 2015 Super Bowl half-time show, which took place on 1 February at the University of Phoenix Stadium in Arizona. During the performance, the 30-year-old singer's backup dancers wore high-waist polka dot bikinis, something similar to what Swift had worn while holidaying with Conor Kennedy on the shores of Hyannis Port, Massachusetts in 2012.

In an interview with Billboard, Russell Brand's estranged wife, said she will not let anyone tarnish her reputation.

"If somebody is trying to defame my character, you're going to hear about it [during the performance]," she said.

Meanwhile, in an interview with GQ Style, Diplo said he faced backlash from Swift's supporters for tweeting that the Shake It Off songstress had a "flat booty".

"All I know is don't ever get into a feud with Taylor Swift. She has like 50 million people that will die for her. It's like an army that's worse than North Korea. You can't step into that arena. That was something I was never prepared for... one of the biggest mistakes of my career was definitely f*****g with her," he said.
