Though they both promoted the airing of a video allegedly showing Heath Ledger using drugs, Entertainment Tonight and sister show The Insider have elected not to broadcast the incendiary clip. "Out of respect for Heath Ledger's family, [we] have decided not to run the... video which has been circulating in the world media," the infotainment mags said in a joint statement.

Meanwhile, Michelle Williams - Ledger's ex-fiancée, and the mother of his 2-year-old daughter - is lashing out against Us Weekly, which in its new cover story posits that the actress once tried to take Ledger to rehab, only to have him refuse. "Much of the tabloid reporting is inaccurate," says the onetime couple's publicist. "This fabricated story of Michelle Williams attempting to bring Heath Ledger to rehab is just one lie among many. The speculation is heinous. Let this family grieve privately."
