Heath's partying got
out of control after
After his breakup from Michelle Williams, Heath Ledger partied more than ever, says his friend. "He had been holed up in Brooklyn for two years and when he was single, he let loose. He was going out much more than he used to." He didn't drink, but reportedly "was using a lot more drugs," says an insider. In November, adds another insider, he went to New York's Beatrice Inn and "was trying to be very secretive about doing mushrooms there with his friends."
