"Hollywood hunk Leonardo DiCaprio has cancelled an appearance at the World Development Summit - despite calling on American President George W. Bush to attend," says the IMDB. This provides further evidence that celebrities like DiCaprio prefer not to remain silent and be thought a fool, rather to open their mouth and prove it.

In addition, major media outlets continue to lap it up, by printing the opinions of celebrities as if they are an expert on the subject. My guess is that they figure celebrities making idiots of themselves will help draw bigger ratings.

It is reminiscent of when CNN-Money took financial advice from singer, Billy Joel, quoting him as saying investors "have a good reason to be scared." This is in spite of admitting that he'd just "checked out of a substance abuse and psychiatric hospital after a 10-day stay -- said he does not have that much exposure to stocks in his own portfolio and said he is generally distrustful of large corporations."
