The song "Let It Die", on new Foo Fighters album Echoes, Silence, Patience & Grace, is widely assumed to be about the relationship between Kurt and Courtney.
It contains the lyric: "A simple man and his blushing bride, intravenous, intertwined… You're so considerate, did you ever think of me?".
Writing on her MySpace, Courtney said: "As for that drummer, well he's hit on me so many times. He's just a very, very conflicted guy about me, which is why he continually writes songs about me to hear he hates me more than anyone else.
"Kurt loathed him more than anyone else [except a journalist]. In his will he made a codicil that Grohl was no longer a member of Nirvana. I just ignored the guy and will continue to do so.
"Dave knows this, and he takes it out on me! Hey, it wasn't my band and it wasn't my idea! It's funny he hates me since I don't think about him.
"He's just a sub-mediocre kind of guy who does this 'nice guy' nonsense. There isn't a word he could he say that would ruffle my feathers, honestly. Anyway, what a fun, fabulous, special evening!"
