Jan-Michael Vincent, who starred in the '80s TV show "Airwolf," is now down to 105 pounds, panhandling in California's Long Beach, shooting up heroin between his toes and supposedly suicidal, his former girlfriend, Lisa Chiafullo, tells the New York Post. Chiafullo, who lives in New Jersey, claims "he may die in two weeks if he doesn't clean up." After getting word about Vincent's condition two days ago from his old friend "Grizzly Adams" star Dan Haggerty, she's reportedly flying to the West Coast Friday to track down the former hunk and get him into rehab. "I called Nick Nolte, Willie Nelson, Cheech Marin, Leon Russell and Kris Kristofferson," Chiafullo told the Post. "No one will help." She says Nelson told her, "Forget it. I'm tired of going through this."
