Jack on Heath: "I Warned Him"

The paparazzi broke the news of Heath Ledger's death to Jack Nicholson in London last night -- and he had an eerie reaction to the news.

The photogs told Jack that Heath overdosed, but right now the evidence is pointing away from a suicide. At a presser today in London, Jack specifically warned the crowd against Ambien, saying he almost drove off a cliff while using the sleep aid. He added that he never knew Heath.
