Katy Perry Attends Kanye Concert; Records Taylor Swift's Diss Song 'Famous'

The "Bad Blood" between two former friends-Katy Perry and Taylor Swift just continue to be bloodier as the "Rise" singer Perry filmed herself during rapper Kanye West's concert in Los Angeles last Tuesday.

The 10-second clip contains Perry making a face simultaneously with West's performance of the song "Famous" as reported by the Huffington Post.

"Famous" is known to be West's diss song for Swift and Perry specifically recorded during the lines, "For all my Southside n*ggas that know me best / I feel like me and Taylor might still have sex / Why? I made that bitch famous!"

Towards the end, Perry cringed and zoomed the camera in, which emphasized her widening eye.

Perry and Swift's clash started to surface back in 2014 after the latter's interview with The Rolling Stone magazine.

The rift between West and Swift began when the former interrupted Swift's speech at the VMAs in 2009 after bagging the Best Female Video Award for her single "You Belong with Me"

In the middle of the speech, West grabbed the mike and said, "Yo, Taylor, I'm really happy for you and I'mma let you finish, but Beyonce had one of the best videos of all time."

This act shocked everyone including Beyonce who later that night requested Swift to join her back on stage.

His intervention was not well received, as an apparently horrified Beyonce invited Taylor back.

Meanwhile, Perry and Swift's roller coaster of emotion rift involves numerous issues including friends, works, and even past lovers.

Perry was even regarded as the inspiration of Swift's "Bad Blood" with lyrics, "Cause baby, now we have bad blood. You know it used to be mad love".

And just recently, Perry released a new fragrance called "Mad Love."

Two days after the Snapchat incident, the two female artists met but avoided each other at Drake's 30th birthday party.
