We're not trying to drum up controversy. She really is dissing her. The full name of the track is "Ur Not That Hot f/ Stack$ & Hollywood Jit (Heidi Montag diss)."
The song begins with a girl impersonating Heidi Montag (who along with Spencer Pratt, recently dissed Brooke Hogan), leaving a faux message for Brooke:
"While it's absurd that Brooke Hogan and Stack$ are even putting out music (term used loosely), we can't object to their bashing Heidi Montag in the intro.
After all, the 'Tag is a girl who thinks 9/11 was an inside job, population control is a myth and the government is trying to control our minds. Spooky stuff.
