Actor Owen Wilson's suicide bid followed a three-day drugs binge on crystal meth and deadly pills dubbed hillbilly heroin, it was revealed last night.
And the troubled star, who overdosed and cut his wrists, had a history of slashing himself, it also emerged.
The news came as police phone records confirmed they rushed to his home after a frantic call about an "attempted suicide".
Owen, 38, is believed to have rounded off his narcotics bender by downing a bottle of powerful Oxycodone painkillers.
They are nicknamed hillbilly heroin because they are cheap, highly addictive and have killed hundreds of US addicts. The Wedding Crashers heart-throb had also been using crystal meth, an equally addictive drug that is often smoked or snorted and produces a rapid high similar to crack.
Medics had to inject him with two powerful anti-narcotics drugs to save him. Owen is feared to have tried to kill himself after seeing photos of ex-love Kate Hudson canoodling with a new man two months after their split.
Kate, 28 - star of How to Lose a Guy in 10 Days - was distraught as she learned the grim news about Owen while shooting a film in Boston.
The actress daughter of Goldie Hawn, seemed numb with shock and was rushed off the set. One insider revealed: "She looked upset and was on the phone, pacing back and forth.
"Then her handlers came out and covered her with an umbrella, she was ushered into a white vehicle and then took off."
However, US reports last night suggested Owen may have attempted suicide after a "vicious quarrel" with a mystery pal at home in Santa Monica, California.
Neighbour Geoffrey White said he had seen two men enter the star's house the previous evening and added: "Someone was with him before this happened. He wasn't alone."
Owen's friends claim he has been "depressed for months" and hinted his black moods may have sparked his break-up with Kate.
One said: "He's such a wonderful person, such a great guy, so smart and nice. We're just hoping he gets better."
Elder brother Andrew is thought to have found him on Sunday afternoon following the suicide scare.
Andrew, actor brother Luke, 35, and dad Robert have all visited him at Cedars-Sinai Medical Centre in Los Angeles, where he was said to be in "good" condition last night.
The drama has left shooting of Owen's two new films - Marley & Me, starring Jennifer Aniston, and Tropic Thunder with Jack Black - in chaos.
