Katy Perry And Taylor Swift Bad Blood Intensifies: Melissa Rivers Slams ‘Wildest Dreams’ Video With ‘Head In A Box’ Comment

Melissa Rivers has reignited the ongoing feud between Katy Perry and Taylor Swift. 

The veteran actress and television host made a comment during a recent episode of "Fashion Police" directed at the two artists. She made a reference to Swift, asking "What kind of dreams does she have left? Katy Perry's head in a box?"

Last month, Perry was reported to be working on a new single with ex-boyfriend Diplo entitled "Crocodile Tears" that serves as a diss song against Swift.

New information suggests, however, that the "Bad Blood" singer isn't concerned about the new song.

"Taylor isn't worried about Katy's diss song about her at all," a source told Hollywood Life.

"If anything, she thinks it will help her out because it'll draw more sales for her own single 'Bad Blood.'"

The revelation sparked rumors on social media that their ongoing feud is a publicity stunt, designed to get attention from fans of both parties. This speculation, however, has not been confirmed. 

A source has since opened up about their ongoing feud and their desire to put their beef to an end. 

"More than anything, Katy wants to make the world forget about Taylor," another source told Hollywood Life. 

"Everywhere she looks, people are talking about Taylor and it makes Katy nauseous." 

Nonetheless, their longstanding rivalry is alleged to involve a number of issues, such as relationship decisions and music lyrics. 

Katy Perry is 30 years old and Taylor Swift is 25 years old.
