Not only has K-Pez joined forces with Taylor's ex Calvin Harris on a ~rumoured~ diss track, but she has reportedly also started dating him.
“[Katy and Calvin] genuinely have a lot in common,” an insider told OK! Magazine.
“It’s icing on the cake for Katy that she can drop this bomb on Taylor. There’s only one goal for Katy now, and that’s for a romance with Calvin to go public.”
“At first, Katy and Calvin were strictly professional, chatting only about their song,” the source reveals.
Then when Katy brought up the Tay Tay beef, Calvin “was more than happy to vent. He poured his heart out and she goaded him on."
Uh oh, better watch out Taylor.
Katy and Calvin are coming for you!
