Hello, I'm Rebecca Field with today's UPI entertainment update on this Wednesday, January 23, 2008. Hollywood is mourning the loss of a loved and admired star. Australian born actor Heath Ledger was found dead at his New York apartment yesterday. He was only 28 years old. There's no confirmation on the cause of death but police say the Oscar nominated actor apparently died of an accidental drug overdose. Ledger was found with prescription drugs near his body. The actor first emerged into the entertainment scene at age 16. He appeared in the Australian show Sweat. In 1998 he played a heartthrob alongside Julia Stiles in 10 Things I hate About You. He's also known for his roles in The Patriot and A Knight's Tale. Two years ago he was for an Academy Award for Brokeback Mountain. On the set of that film, he and actress Michelle Williams began dating and soon after had a daughter Matilda.

Friends of Winehouse tell People magazine everyone knows she should get treatment. Some stars are promising not to cross writer's picket lines at the Oscars.
