Katy Perry has a not-so-nice surprise in store for her longtime enemy, Taylor Swift.
The 31-year-old singer is currently in the process of creating her new album, which will be complete with a T-Swift diss track!
"Katy Perry's new album is on the way and she's been buried in meetings with her label execs over at Capitol to make sure it blows her competition out of the water," an insider told RadarOnline.com exclusively.
