LALATE broke to you tonight news of the shocking Heath Ledger Drug Party Video.

Now news from US Magazine that Ledger refused to go to rehab in battling a three year addiction on heroin, cocaine and a variety of pills. When taken to rehab just weeks after his Oscar red carpet appearance, Ledger according to US refused to seek treatment.

Says US:

“Heath Ledger’s battle with alcohol and drugs was so harmful to his relationship with Michelle Williams that she tried to get him to enter rehab, Us Weekly reports in its latest issue, on newsstands now.

“For three years, Williams was a firsthand witness to the gifted actor’s use of alcohol and drugs, including cocaine, heroin and “a variety of pills,” says a Ledger confidant.

“In March 2006 – just weeks after the couple walked the Oscars red carpet and when daughter Matilda was only five months old – Williams drove Ledger to Promises Treatment Center in Malibu, California, the confidant tells Us Weekly.

“Ledger refused to check in, instead swaying her with a pledge to clean up.

“Even after the couple realized “they were in way over their heads,” according to a source, and split in September 2007, two sources tell Us that Williams demanded Ledger be drug-tested before his visitations with Matilda.”
