Actor Tom Arnold staged an intervention to convince his pal Davis to enter a rehab program to kick his addictions late last year (09).
Davis, the grandson of billionaire oilman Marvin and brother to socialite Brandon, reportedly left the unit on New Year's Eve (31Dec09) but was admitted to Cedars-Sinai Medical Center in Los Angeles last week, sparking reports he had suffered an overdose.
But his spokesperson has hit back at the allegations, insisting Davis suffered complications from a chronic staphylococcus infection and a skin inflammation, known as cellulitis.
His spokesperson tells the New York Post, "(Davis) did not overdose. Nor is he dead... Jason has been very public about his past use, and will continue to speak out on addiction and recovery."
Davis also insists he is making steps to kick his addictions, adding: "The prospect of dying young like Casey Johnson, Brent Shapiro and so many friends of mine is really scary. I am taking steps to get well and your thoughts and prayers are deeply appreciated."
