Despite telling ABC's Good Morning America that he never prescribed the powerful narcotics that may have lead to Michael Jackson's death ("I didn't give him any of that crap"!) Dr. Arnold Klein is now admitting that he gave the King of Pop Demerol.

Jackson's dermatologist told CNN's Larry King Live last night that Demerol was the strongest drug he prescribed the late pop icon, and he only administered the medication "on occasion" to sedate him. Klein added that he doesn't know how Jackson got Diprivan, an even stronger sedative typically used by anesthesiologists in hospitals.

Think he's telling the truth?
