She dabbled in music again with the release of the film "Happy Feet", in which she covered Queen's "Somebody to Love" and Earth, Wind & Fire's "Boogie Wonderland".

George Miller always wanted one person to do both speaking and the singing. I said, 'I can sing,' and I asked him to give me a shot. I don't think he took me very seriously, because most actors say they can do most things."
