Miley Cyrus is building up a new reputation...of being a bitch.
First, there was tension between her and fellow Disney stars, Selena Gomez and Demi Lovato, when Miley and her back-up dancer/best friend, Mandy posted a parody of the two girls on their YouTube account.
Miley later gave Selena and Demi a very insincere apology.
Now, Miley's duking it out with Katy Perry. The 23-year-old singer of I Kissed a Girl recently revealed in an interview that she would love to share a Madonna-Britney-esque kiss with Miley.
Miley's response? "No thanks. She sang on my record. So I think she's kind of getting back at me, because she was doing harmonies and backgrounds."
Perez Hilton contacted Katy, who said, "6 weeks in a row at number one. And she recorded two of my old songs."
Team Katy for this one!
